Hello there!

(a + b)² = a² + 2ab + b²

= a² + b² + 2ab

= 16 + 2(8)

= 16 + 16

= 32

As always, it is my pleasure to help students like you!

Hope this helps.

Solve thr proprtion for x. 14/20=17/x+12
Readme [11.4K]
<span>Solve thr proprtion for x. 14/20=17/x+12</span>cross multiply:
14 * x + 12 = 20 * 17
Simplifying14 * x + 12 = 20 * 17
Reorder the terms:14 * 12 + x = 20 * 1712 * 14 + x * 14 = 20 * 17168 + 14x = 20 * 17
Multiply 20 * 17168 + 14x = 340
Solving168 + 14x = 340
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-168' to each side of the equation.168 + -168 + 14x = 340 + -168
Combine like terms: 168 + -168 = 00 + 14x = 340 + -16814x = 340 + -168
Combine like terms: 340 + -168 = 17214x = 172
Divide each side by '14'.x = 12.28571429
Simplifyingx = 12.28571429
