(y + 7)^2 = (y + 7)(y + 7)
Multiply all the terms in the first parenthesis to all the terms in the 2nd parenthesis:
y * y = y^2
y * 7 = 7y
7 * y = 7y
7 * 7 = 49
So we have:
y^2 + 7y + 7y + 49
Combine like terms:
y^2 + 14y + 49
The answer should be 8/6 or simplified as 4/3 or mixed number as 1 and 1/3.

Answer:
W=7 L= 16
Step-by-step explanation:
you start off with
P=2L+2W (the equation to find perimeter)
the equation gives you the perimeter = 46
so you plug that in
46=2L +2W
then it says the length IS (which also means equals) 9 plus the width
so you then get another equation:
L=9+W
you take that and plus it into the first equation/ substitute the new equation for L in the first equation
46=2(9+W)+2W
you solve that and get
w=7
you plus the 7 in for the w
L=9+7 = 1
W=7 L=16
