you answer is b) -x^2-4x+7
Answer:
B
Step-by-step explanation:
4x² - 7x + 9 - (5x² - 3x + 2) ← distribute by - 1
= 4x² - 7x + 9 - 5x² + 3x - 2 ← collect like terms
= (4x² - 5x² ) + (- 7x + 3x ) + (9 - 2)
= - x² - 4x + 7 → B

Let c represent the cost and r represent the number of rooms, then
a.) c = 22r
b.) 200 = 22r
r = 200/22 = 9.09 ≈ 9 rooms
c.) 200 - 40 = 22r
r = 160/22 = 7.27 ≈ 7 rooms
Answer
The answer is A. y = x²
5*2 = 10
3^2 = 3*3 = 9
10 + 9 = 19
Answer: 19
So 7 yards of fabric
total cost=yards times cost per yard
total cost=45.43
yards=7
45.43=7 times cost per yard
divide both sides bby 7
6.49=cost per yard
the cloth costs $6.49 per yard
