Did Cherise use algebra tiles to correctly represent the product of (x – 2)(x – 3)?

A.No, she did not multiply the x-tiles by the negative integer tiles correctly.

B.No, she did not multiply the negative integer tiles by the other negative integer tiles correctly.

C.No, she did not add the terms together correctly.

D.Yes, the product is x2 – 5x – 6.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
