Answer:

2(3x - 4)(3x + 4)

Step-by-step explanation:

Factorizing the below expression requires factoring common term.

[tex]18 {x}^{2} - 32[/tex]

Obviously 2 is common to both 18 and 32. Thus, the answer is:

[tex] = 2(9 {x}^{2} - 16)[/tex]

=2(3x - 4)(3x + 4)

Answer:

the answer above was a little confusing to me so i thought i would just give the answer straight up: 2(3x+4)(3x-4)

Length of side of base is 5.45

Step-by-step explanation:

Here, since the base is an equilateral triangle and it is given that height of the prism is equal to that of the base, measures of base and height are equal.

⇒ Volume = 1/2 × b × h × h (b and h are equal)

⇒ 81 = 1/2 × b³

⇒ b³ = 162

⇒ b = ∛162 = 5.45

There are 20 dimes and 80 quarters

Solution:

Let "d" be the number of dimes

Let "q" be the number of quarters

1 dime = $ 0.10

1 quarter = $ 0.25

Panchito Pantera has 100 coins

Therefore,

number of dimes + number of quarters = 100

d + q = 100 ----------- eqn 1

He has a total of $22. Thus we frame a equation as:

number of dimes x 0.10 + number of quarters x 0.25 = 22

[tex]d \times 0.10 + q \times 0.25 = 22[/tex]

0.1d + 0.25q = 22 --------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

d = 100 - q ------- eqn 3

Substitute eqn 3 in eqn 2

0.1(100 - q) + 0.25q = 22

10 - 0.1q + 0.25q = 22

0.15q = 22 - 10

0.15q = 12

Divide both sides by 0.15

q = 80

Substitute q = 80 in eqn 3

d = 100 - 80

d = 20

Thus there are 20 dimes and 80 quarters

You haven't provided any figure, so I could help you in a general way providing my own figure which is attached below. In order to illustrate transformations, let's choose the third one:

[tex]T:(x - 6, y - 2)[/tex]

For this transformation, every point on the original figure is translated 6 units to the left and 2 units down. So quadrilateral ABCD is transformed into quadrilateral EFGH as follows:

[tex]A(10,4) \\ \\ B(14,2) \\ \\ C(14,6) \\ \\ C(10,-2) \\ \\ \\ E \rightarrow (10-6,4-2) \rightarrow (4,2) \\ \\ F \rightarrow (14-6,2-2) \rightarrow (8,0) \\ \\ G \rightarrow (14-6,6-2) \rightarrow (8,4) \\ \\ H \rightarrow (10-6,-2-2) \rightarrow (4,-4)[/tex]

Question:

The equations in this system were added to solve for x. What is the value of x? -2x+y=8 5x-y=-5 3x=3

Options:

x = negative 3

x = negative 1

x = 1

x = 3

Answer:

The value of x is 1

Solution:

Given system of equations are:

-2x + y = 8 ------- eqn 1

5x - y = -5 ------- eqn 2

The above equations are added to solve for "x"

Add eqn 1 and eqn 2

-2x + y + 5x - y = 8 - 5

Combine the like terms

-2x + 5x + y - y = 3

Add the like terms

3x + 0 = 3

3x = 3

Divide both sides of equation by 3

x = 1

Thus the value of x is 1

The number of fringes at [tex]d=-2[/tex] is given as 20.

Step-by-step explanation:

Question

A Galapagos cactus finch population increases by half every decade. The number of finches is modeled by the expression

,

where d is the number of decades after the population was measured. Evaluate the expression for d = −2

Given :

The number of  finches is modeled by the expression  :

⇒ [tex]45\cdot1.5^d[/tex]

where [tex]d[/tex] is the number of decades after the population was measured.

To evaluate the expression for d=-2

Solution:

In order to evaluate the given expression to find the number of finches at [tex]d=-2[/tex], we will plugin [tex]-2[/tex] for [tex]d[/tex] in the expression and simplify it.

Plugging in [tex]d=-2[/tex] in the expression:

⇒ [tex]45\cdot 1.5^{-2}[/tex]

Using negative exponent property. [[tex]a^{-x}=\frac{1}{a^x}[/tex]

⇒ [tex]45\cdot \frac{1}{1.5^2}[/tex]

⇒ [tex]45\cdot \frac{1}{2.25}[/tex]

⇒ [tex]20[/tex]   (Answer)

Thus, the number of fringes at [tex]d=-2[/tex] is given as 20.

This means the number of fringes two decades ago was 20.

This remains the same on the moon as on Earth.  --> MASS

This results from the pull of gravity.  --> WEIGHT

This relates to the amount of matter in an object.  --> MASS

This will change in space.  --> WEIGHT

mass is a SCALAR, weight is a VECTOR

Step-by-step explanation:

In physics:

- The mass of an object is a scalar quantity that gives a measure of the "amount of matter" in an object. It is an intrinsec property of the object, therefore its value does not depend on the location of the object.

- The weight of an object is the force of gravitational attraction exerted on the object. Being a force, it has a magnitude and a direction. Its magnitude is given by

[tex]F=mg[/tex]

where m is the mass of the object and g is the acceleration due to gravity at the location of the object. Therefore, its value depends on the location.

Now we can identify correctly each statement given:

This remains the same on the moon as on Earth.  --> MASS

This results from the pull of gravity.  --> WEIGHT

This relates to the amount of matter in an object.  --> MASS

This will change in space.  --> WEIGHT

Step-by-step explanation:

Answer:

2t = 81

t = 40.5 is the answer

answer is c

all you do is divide 40 by 2/3 to get the answer :D

Answer: Weight is 60

Explanation:

So lets look at what we are given:

w (weight) * 2/3 = 40 pounds

(short explanation is you times 40 by 3/2)

We want to solve for weight there are a few ways to do this but the easiest one is to times both sides of the equation by the reciprocal of 2/3. Which is 3/2. That will cancel our the 2/3 and leave only "w" on the left side.

w = 40 * 3/2

Answer: [tex]\frac{1}{4}\ cups[/tex]

Step-by-step explanation:

For this exercise it is important to analize the information given in the exercise.

 According to the data provided in the exercise, the recipe says that [tex]\frac{1}{2}\ cups[/tex]  of Parmesan serves four people.

 The, let be "x" the amount of cups of Parmesan cheese that Cordelia will use for her brother's proposal dinner.

In this case, since the proposal dinner is for two people, you can set up the following proportion:

[tex]\frac{4}{\frac{1}{2}}=\frac{2}{x}[/tex]

Finally, you must solve for "x" in order to find its value, as you can observe below:

[tex]8=\frac{2}{x}\\\\8x=2\\\\x=\frac{2}{8}\\\\x=\frac{1}{4}[/tex]

Therefore, knowing the value of "x", you can determine that Cordelia will use [tex]\frac{1}{4}\ cups[/tex]  of Parmesan cheese for the proposal dinner.

A total of $170.86 will be spent if you buy shirts for $44.11

Step-by-step explanation:

Step 1:

Let the cost of shirts be $x.

Given that, one pair of jeans costs $39.95, 2 pairs cost 2 * $ 39.95 which is $79.9. Jacket costs $45.99.

Step 2:

Create an equation with this given data.

$170.86 = $x + $79.9 + $45.99

Step 3:

Calculate the value of x from this equation to get the cost of shirts.

$170.86 = $x + $125.89

$x = $170.86 - $125.89

$x = $44.11

Answer:

  C.  21 in² . . . . your answer selection is correct.

Step-by-step explanation:

The area of a triangle is given by the formula ...

  A = 1/2bh

where b represents the base of the triangle, and h represents the height of the opposite vertex above that base.

The figure shows you that half the base is 3 in and the height is 7 in, so the area is ...

  A = (1/2b)h = (3 in)(7 in) = 21 in² . . . . matches choice C

The answer would be properly V = 1/3*pi*r²*h ..

V = 1/3*pi*12²*8 ..

V = 384*pi.
