Juan wants to know the length of the sides of a square tabletop. The tabletop has an area of (x^2-16x+64) square feet. Which binomial represents the length of a side of the tabletop? A. x-4
B. x-8
C. x+8
D. x-2

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

$32,660

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
