The length of a rectangle is nine inches less than twice the width. If the perimeter of the rectangle is 84 inches, find the dimensions of the rectangle. Please help its algebra

(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

15.36 per mile

but forgot to round

i am pretty sure

false

inverse variation is not exponential
