Area of rectangle = length x width
(x + 12)(x - 5$
Fist do the parentheses that come first one top then do the second set of parentheses, then add those and you have your answer
X^2 -15x +54 = 0 for you can factor it easy just you need getting two numbers with sum equal -15 and product equal 54
-15= (-9)+(-6) and (-9)*(-6)= -54 in this way will get
x^2 -15x +54 = (x-6)(x-9)
hope helped
The answer is 5680 :) thank me later
