Answer:
Step-by-step explanation:
Area of the good part= area of whole roof - area of bad part
Since the roof is a square roof, the area will be calculated using the formulae for area of a square
Area of a square =length²
Area of good part =(x+12)²-x²
A= {(x+12)(x+12)} - x²
A = (x²+12x+12x+144) -x²
Open the bracket and rearrange the equation
A= x²-x²+24x+144
A=(24x+144) ft
These are the steps good luck
Theres an app called slader. If you look up what your school book is it will give you all the answers
A. -14x+21
because -7 times 2x is -14x and -7 times -3 is 21
Answer:
Zero.
