Question 246669: Need help in solving this:
The area in square feet for a rectangular deck is given by A = x^2 + 6x +8
a) What would be the area if x was 6?
b) Remembering that Area = Length * Width, factor the above equation. If the width of
the deck is x + 2, what is the length?
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! a) If x=6, then A=x^2 + 6x +8
A=6^2 +6*6+8
A=36+36+8
A= 80 square units
b) If A=x^2 +6x+8
A=(x+2)(x+4)
A= W*L
If x+2 = width, then L=x+4.
