The area ,a of a rectangle is 120x2+78x-90and the length i , if the rectangle is 12x+15 which of the following gives the width w of the rectangle a. 9x+4 b.10x-19 c.10x-6 d.8x-6

100% sure it is 10x-6

Hope it helps!

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
