What is the completely factored form of 8x^2-50?

a) 2(x+5)(x-5)
b) 2(2x-5)(2x-5)
c) 2(2x+5)(2x+5)
d) 2(2x+5)(2x-5)

your answer is d 2,500

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
