for an unknown polynomial function p(x),p(2)+4=4, which binomial is a factor of p(x)?
Answer:i think it is 0
Step-by-step explanation:
You can use the fact that if (x-root) is a factor of a single variable polynomial function p(x) = 0
A binomial factor of p(x) is (x-2)
How to get factor of a single variable polynomial function if we know its one of the roots?Let its root be x = k
Then we have one of the factor of polynomial as (x-k)
What is a root of a single variable polynomial function p(x) ?Root of a polynomial function p(x) is a value of x such that putting that value in place of x makes the output 0.
Thus, if x = k is a root of the polynomial p(x), then
p(k) = 0
How to get a factor of the considered polynomial function?Since it is given that
p(2) + 4=4
thus,
p(2) = 4-4 = 0
Thus, x = 2 is a root of the polynomial function, and thus, using the aforesaid conclusions, we have (x-2) as one of the factors of the considered polynomial function.
Thus,
A binomial factor of p(x) is (x-2)

3 brothers have 58 years in total. How old is the youngest brother if 3/4 of his age equals to 2/3 of middle brother's age and 3/4 of youngest brother's age equals to half of oldest brother's age?
Step-by-step explanation:
Let O represents older brother
M represents middle brother
& Y represents younger brother.
Therefore, according to the given condition:
[tex] \frac{3}{4} y = \frac{2}{3} m = \frac{1}{2} o \\ \\ \therefore \: \frac{3}{4} y = \frac{2}{3} m \\ \implies \: m = \frac{3}{2} \times \frac{3}{4} y = \frac{9}{8} y \\ \\ next \: \: \frac{3}{4} y = \frac{1}{2} o \\ \implies \: o = \frac{2}{1} \times \frac{3}{4} y = \frac{3}{2} y \\ \\ \because \: o + m + y = 58 \\ \\ \therefore \: \frac{3}{2} y + \frac{9}{8} y + y = 58 \\ \\ \therefore \: \frac{12}{8} y + \frac{9}{8} y + \frac{8}{8} y = 58 \\ \\ \therefore \: \frac{29}{8} y = 58 \\ \\ \therefore \: y = 58 \times \frac{8}{29} \\ \\ \therefore \: y = 2 \times 8 \\ \\ \therefore \: y = 16 \: years[/tex]

3. Bill's baseball bag weighs 4 pounds. If he takes out a pair of cleats
that weigh 6 ounces, how much will his bag weigh?
Answer:
58 ounces
Step-by-step explanation:
16 x 4=64 - 6=58 ounces
Final answer:
After converting the weight of the cleats from ounces to pounds, the new weight of Bill's baseball bag is determined to be 3.625 pounds by subtracting 0.375 pounds (weight of the cleats in pounds) from the original 4 pounds.
Explanation:
The subject of this question is Mathematics, specifically dealing with unit conversion and simple subtraction of weights. To determine the new weight of Bill's baseball bag after removing the cleats that weigh 6 ounces, we need to first convert the ounces to pounds, since the weight of the bag is given in pounds.
There are 16 ounces in one pound. Therefore, 6 ounces is equivalent to 6 ounces \/ 16 ounces per pound = 0.375 pounds. Starting with the original weight of the bag which is 4 pounds, subtracting the weight of the cleats in pounds will give us the new weight of the bag.
4 pounds - 0.375 pounds = 3.625 pounds. This is the weight of Bill's baseball bag after the cleats are removed.

30 kg into 5:3 ratio
Answer:
18.75 Kg : 11.25 Kg
Step-by-step explanation:
Sum the parts of the ratio, 5 + 3 = 8 parts
Divide 30 Kg by 8 to find the value of one part of the ratio
30 Kg ÷ 8 = 3.75 Kg ← value of 1 part of the ratio, thus
5 parts = 5 × 3.75 Kg = 18.75 Kg
3 parts = 3 × 3.75 Kg = 11.25 Kg

3: 36-7x=-7(x-5)
Answer:
1) one solution
2) Infinitely many solution
3) no solution
Step-by-step explanation:
The first equation is -14-8x=-2(-3x+7)
Let us expand the right hand side to get:
-14-8x=-2*-3x+-2*7
We multiply -14-8x=6x-14
We group similar terms to get:

How do you find a volume of a sphere? Please explain. (Also if you can please someone answer the other questions I asked but it has not been answered.)
Thanks!
Answer:
V = (4/3)πr³
Step-by-step explanation:
The formula usually used to find the volume of a sphere is ...
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
where r represents the radius of the sphere.
The actual math involved will depend on what information about the sphere you are given. If you are given the radius or diameter (twice the radius), then this formula will be directly useful.
To determine the volume of a sphere, use the formula V = ([tex]\frac{4}{3}[/tex])πr³. Measure the radius, cube it, multiply by pi, and then multiply by 4/3.
To find the volume of a sphere, you use the formula:
V = ([tex]\frac{4}{3}[/tex])πr³
Here, V stands for volume, r represents the radius of the sphere, and π (pi) is approximately 3.14159.
Step-by-Step Explanation:
Measure the radius r of the sphere.Cube the radius (multiply it by itself three times): r³.Multiply the cubed radius by π (pi).Multiply the result from step 3 by 4/3.Ticketmaster charges $95 for Ariana

there are 25 animals in the field. Some are horses, some are ducks. There are 84 legs in all. How many of animal are in the field?
Answer:
Ducks = 8
Horses = 17
Step-by-step explanation:
From the question;
Total number of animals = 25 Total number of legs = 84 legsWe are required to determine the number of ducks and horses;
We need to know that;
A duck has two legs while a horse has four legs;
Assuming there were x ducks and y horses
Then;
x + y = 25 ................................Eqn 1
And;
2x + 4y = 84 .............................Eqn 2
Solving the two equations simultaneously we can get the number of each animal.
x + y = 25
2x + 4y = 84
Multiplying the first equation by 2, we get
2x + 2y = 50
2x + 4y = 84
Subtracting the two equations;
2x + 2y = 50
2x + 4y = 84
........................................................
- 2y = -34
y = 17
Solving for x
x = 25 -17
= 8
Therefore; there were 8 ducks and 17 horses in the field

Which quadrilateral can be inscribed in a circle?
A) A
B) B
C) C
D) D
Answer:
The correct option is A
Therefore the quadrilateral in the option A can be inscribed in a circle.
Step-by-step explanation:
Given:
Four Quadrilateral, A ,B ,C ,D in the figure below.
For a quadrilateral to be inscribed in a circle we required opposite angles must be supplementary, that is it should add up to 180°.
So from the four given quadrilateral we have only in quadrilateral A the opposite angles are supplementary.
Quadrilateral A :
Consider the quadrilateral PQRS where
∠SPQ = 91°
∠PQR = 101°
∠QRS = 89°
∠SPQ and ∠QRS are opposite angles and their sum is 180°
[tex]\angle SPQ+\angle QRS = 91+89 =180[/tex]
Others in option B, C , and D opposite angles are not supplementary hence cannot inscribe in a circle.
Therefore the quadrilateral in the option A can be inscribed in a circle.
Answer:
c Mark me as the brainiest
Step-by-step explanation:
A quadrilateral that can be inscribed in a circle has vertices that lie on a single circle. A distinguishing property of such quadrilaterals is that they have opposite angles adding up to 180°. Non-rectangular parallelograms cannot be inscribed in circles, because their opposite angles are equal rather than supplementary.

What are all of the Angle measures
Answer:Type of Angle Description
Acute Angle is less than 90°
Right Angle is 90° exactly
Obtuse Angle is greater than 90° but less than 180°
Straight Angle is 180° exactly
Step-by-step explanation:
Answer:
∠ABC = 62°, ∠DBE = 62°, ∠CBE = 118°, ∠ABD = 118°
Step-by-step explanation:
Solving for xWe can say that angle ABC and angle DBE are vertically opposite angles because there are only two intersecting lines. Vertically opposite angles are equal so we can form an equation:
4x + 2 = 5x - 13
5x - 4x = 2 + 13
x = 15
Angles ABC and DBENow we can substitute x into the equation and find out the value for angles ABC and DBE.
4(15) + 2 = 60 + 2 = 62°, just to make sure we need to substitute x into the other equation to see whether we get the same answer:
5(15) - 13 = 75 - 13 = 62°, now we can confirm that angles ABC and DBE are 62°.
Angles CBE and ABDNow we can use the rule, angles on a straight line add up to 180°, to find the other two angles, because these two angles are vertically opposite, they are also equal to each other.
180 - 62 = 118°
Angles CBE and ABD are both 118°
