Question

PLEASE HELP ME I BEG I REALLY NEED HELP WITH THIS PROBLEM!

Answer 1

Area = length x width

x² + 12x = l * x


A.  

First, you factor x from x² + 12x

$x^{2} +12x=x(x+12)$

area = x (x+12)

area = (x+12) * x

Length = x + 12



B.

If x = 10,
l = x + 12 = 10 +12 = 22
length = 22
and
Area = x² + 12x = 10² + 12(10) = 100 + 120 = 220
area = 220
        

Hope this helps :)
