Factor the expression below. x^2+9x+8
Answer:
(x + 1)(x + 8)
Step-by-step explanation:
Given
x² + 9x + 8
Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (+ 9)
The factors are + 1 and + 8, since
1 × 8 = 8 and 1 + 8 = 9, thus
x² + 9x + 8 = (x + 1)(x + 8)

The difference between two numbers is 52 .Five times the smaller is equal to 4 more than the larger. What are the numbers?
The larger number is 66 and the smaller number is 14.
Step-by-step explanation:
Let,
The larger number = x
The smaller number = y
According to given statement;
x-y=52 Eqn 1
5y = x+4 Eqn 2
From Eqn 2
x = 5y-4 Eqn 3
Putting value of x from Eqn 3 in Eqn 1
[tex]5y-4-y=52\\4y=52+4\\4y=56[/tex]
Dividing both sides by 4
[tex]\frac{4y}{4}=\frac{56}{4}\\y=14[/tex]
Putting y=14 in Eqn 3
[tex]x=5(14)-4\\x=70-4\\x=66[/tex]
The larger number is 66 and the smaller number is 14.

5x+17+9x+23=180 solve for x
Answer:
x=10
Step-by-step explanation:
First combine like terms:
14x + 40 = 180
Second subtract 40 from both sides:
14x = 140
Third divide both sides by 14:
x = 10
Is 2(3a-2)+4a equivalent to 10a-2
After simplifying the expression 2(3a-2)+4a, we get 10a-4, which is not equivalent to 10a-2 due to a difference of 2.
Explanation:To determine if the expression 2(3a-2)+4a is equivalent to 10a-2, we must simplify the former expression.
First, distribute the 2 into the parenthesis: 2 × 3a is 6a, and 2 × -2 is -4. So we get 6a - 4.
Next, we add the 4a that is outside the parenthesis to the 6a we got after distribution: 6a + 4a equals 10a.
Now we have 10a - 4. This is close to 10a-2 but there is a difference of 2. Therefore, the two expressions are not equivalent.

1) The figure at the top is a parallelogram; the area is A = bh; where b is the base and h is the height; use properties of special right triangles to find h, and the area of the parallelogram
a) Read the problem once and state what is the problem about?
Answer:
[tex]10 \sqrt{3} {cm}^{2} [/tex]
Step-by-step explanation:
The area of a parallelogram is A=bh.
From the diagram, the base is b=5m
We now use the properties of 30°-60°-90° right angle to find h.
The sides of this triangle is given by x,½x,½x√3
Where x is 4
Therefore we have 4,2, 2√3
So we have h=2√3m

celine mixes raisins and peanuts to make a snack. she uses 0.75 cup raisins for every 0.5 cup peanuts. write a proportion and use it to find the number of cups of raisins she uses if she uses 4.25 cups of peanuts
Answer:
6.375 cups of raisins
Step-by-step explanation:
The ratio of raisins to peanuts is 3:2. This is because 0.5 divided by 2 and then multiplied by 3 is equal to 0.75.
So to find the number of raisins we need to divide the number of peanuts by 2 and then multiply it by 3:
(4.25 ÷ 2) × 3 = 6.375
Answer:
Step-by-step explanation: they both equal 2x + 4
2x + 4=2(x + 4)
2x + 4= (2 X x) + (2 X 4)
2x + 4= 2x + 4
Write a linear equation that passes through the point (2,-9) and has a slope of -5
Answer:
y=-5x+1
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=-5(x-2)
y+9=-5x+10
y=-5x+10-9
y=-5x+1
The linear equation that passes through the point (2, -9) with a slope of -5 is y = -5x + 1.
To find the linear equation, we use the point-slope form of a line, which is:
y - y₁ = m(x - x₁)
Here,
m is the slope and (x₁, y₁) is a point on the line.
Given:
Slope (m): -5Point (x₁, y₁): (2, -9)Substitute the values into the point-slope form equation:
y - (-9) = -5(x - 2)
Simplify the equation:
y + 9 = -5(x - 2)y + 9 = -5x + 10y = -5x + 10 - 9y = -5x + 1So, the linear equation in slope-intercept form is y = -5x + 1.
identify this coefficient 8x
Answer:
8
Step-by-step explanation:
The term 8x is a product (as is any term). It is the product of a constant coefficient (8) and a variable (x). The "coefficient" is the multiplier of the variable of interest, so is 8 in this term.
_____
The word "coefficient" is often used to refer to the constant multiplier in any term. For example, in the term 6xy, if we just ask for the coefficient, we are interested in the value 6.
On the other hand, if we ask for the coefficient of y in that term, we expect to be told it is 6x. That is, the "coefficient" is the multiplier of the specified variable or constellation of variables.
The coefficient in the expression 8x is the number 8, which is the numerical factor that multiplies the variable x.
Identifying the Coefficient in the Expression 8x
To identify the coefficient in the expression 8x, we need to recognize that a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. In the case of 8x, the coefficient is 8. This means that 8 is the number by which the variable x is being multiplied. Coefficients play a crucial role in equations and functions, as they determine the proportionality and scale of the variable's effect within the expression.
For example, if x represents the number of units sold, and each unit contributes 8 units of value, the expression 8x would represent the total value contributed by all units combined.

Answer:
6
Step-by-step explanation:
This is a disguised GCF problem. If Jacqueline wants to use all the flowers she has, she must find the greatest common factor of the their numbers.
1. Determine the prime factors of each number and mark those that are common
The prime factors of 42 are 2 × 3 × 7 = 42
The prime factors of 36 are 2 × 2 × 3 × 3 × 3 = 36
The prime factors of 54 are 2 × 3 × 3 × 3 = 54
2. Multiply the common factors
The common prime factors of 42, 36. and 54 are 2 and 3.
The greatest common factor is 2 × 3 = 6.
Jacqueline can make six bouquets, and each will contain seven tulips, six carnations, and nine daffodils.

Can someone answer this question please answer it correctly and show work please
Answer:
First Problem: $50.15
Second Problem: $20,468
Step-by-step explanation:
First Problem: If the original price is $41.00 and the discount is $6.15
41.00 - 6.15 = $34.85 is the discounted price
34.85 / 41.00 = 0.85 -> this shows the amount that you pay from the original price
So if the other product costs $59.00 you just do 59.00 * 0.85 = $50.15
This shows that %85 of the original cost is what you pay.
Second Problem: So, the first amount sold is 160 tickets and the price for each ticket is $59.50.
160 * $59.50 = $9,520 for the afternoon batch
If they sold %15 more in the evening that means that they sold 160 tickets plus another %15 of the 160.
160 * 1.15 = 184 tickets sold in the evening
184 * $59.50 = $10,948 for the evening batch
So they sold a total of $9,520 + $10,948 = $20,468
Answer:
44) $50.15
45) $20,468
Step-by-step explanation:
44) $ off sweater = 6.15
41.00 - 6.15 = 34.85
6.15 ÷ 41.00 = 0.15 = 15% discount
$59.00 - 15%
$50.15
45)
Afternoon = 160 tickets
Evening = 15% more = 160 + 15% = 184 tickets
160 + 184 = 344 tickets total
344 * $59.50 = $20,468

Seven times a number plus three times another number equals negative one. The sum of the two numbers is negative three. What are the numbers’?
Answer:
ur numbers are 2 and -5
Step-by-step explanation:
7x + 3y = -1
x + y = -3......x = -3 - y
7(-3 - y) + 3y = -1
-21 - 7y + 3y = -1
-7y + 3y = - 1 + 21
-4y = 20
y = -20/4
y = -5 <====
x = -3 - y
x = -3 - (-5)
x = -3 + 5
x = 2 <====
Answer: The numbers are 2 and -5
Step-by-step explanation:
7x+3y=-1 ...(equation 1)
x+y=-3 ...(equation 2)
x+y=-3
Broken down, we have x=-3-y
Substitute x=-3-y into equation 1
Then we have 7(-3-y) +3y=-1
Which is -21-7y+3y=-1
which is -21-4y=-1
-4y=-1+21=20
y=-20/4=-5
y=-5
Substitute y=-5 into equation 1
x+y=-3
x-5=-3
x=-3+5=2
x=2
