Answer:
Carpet= $2,400
Laminate=$2,720
Vinyl=$2,144
Step-by-step explanation:
375/100=3.75
3.75*640=2,400 (Carpet)
340/80=4.25
4.25*640=2,720 (Laminate)
402/120=3.35
3.35*640=2,144 (Vinyl)
Answer:
Below
Step-by-step explanation:
The Carpet is = $2,400
The Laminate is=$2,720
The Vinyl is=$2,144
375/100=3.75
(Carpet)3.75*640=2,400
340/80=4.25
(Laminate)4.25*640=2,720
402/120=3.35
(Vinyl)3.35*640=2,144

Solve the Quadratic Equation: 2(x - 5)^2 = 18
Answer:
x=2 or x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x2−20x+50=18
Step 2: Subtract 18 from both sides.
2x2−20x+50−18=18−18
2x2−20x+32=0
Step 3: Factor left side of equation.
2(x−2)(x−8)=0
Step 4: Set factors equal to 0.
x−2=0 or x−8=0
x=2 or x=8
Answer:
1. x = 8
2. x = 2
Step-by-step explanation:
2 • (x - 5)2 - 18 = 0
2.1 Evaluate : (x-5)2 = x2-10x+25
3.1 Pull out like factors :
2x2 - 20x + 32 = 2 • (x2 - 10x + 16)
3.2 Factoring x2 - 10x + 16
The first term is, x2 its coefficient is 1 .
The middle term is, -10x its coefficient is -10 .
The last term, "the constant", is +16
Step-1 : Multiply the coefficient of the first term by the constant 1 • 16 = 16
Step-2 : Find two factors of 16 whose sum equals the coefficient of the middle term, which is -10 .
-16 + -1 = -17
-8 + -2 = -10 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and -2
x2 - 8x - 2x - 16
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-8)
Add up the last 2 terms, pulling out common factors :
2 • (x-8)
Step-5 : Add up the four terms of step 4 :
(x-2) • (x-8)
Which is the desired factorization
2 • (x - 2) • (x - 8) = 0
4.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.

Scenario:
A stack of n small cups has a height, h, in centimeters of h=1.5n+6.
A stack of n large cups has a height, h, in centimeters of h=1.5n+9.
Using G00gle Draw, or by hand, graph the equations for each cup on the same set of axes. Make sure to label the axes and decide on an appropriate scale.
For what number of cups will the two stacks have the same height?
Answer:
The lines will never intersect.
Step-by-step explanation:
The slope of the cups is the same, 1.5. The y-intercept of the small cups is 6
The y-intercept of the big cups is 9.
This means that the lines will never intersect because they are parallel lines and have the same slope but different y-intercepts.

There are 15 girls in the class and 8 boys. Lauren says that the ratio of girls to boys is equivalent to 30 : 18. Is Lauren correct?
Answer:
No
Step-by-step explanation:
If 15 x 2=30 and 8x2=16 not 18 it’s incorrect
Answer:
No, Lauren is not correct because the ratio is actually 15:8 this is because the ratio represents the number of boys to girls. The only way to show this equation in ratio notation would to say 15:8. Therefore Lauren is incorrect.
