Answer:
Area = 77 yd²
Step-by-step explanation:
Width = w
Length = w+4
Perimeter =36
Perimeter = L + L + w + w
36 = w+4+w+4+w+w
4w+8 =36
Subtract 8 from both sides
4w = 36 - 8
4w =28
Divide both sides by 4
W= 28/4
W= 7yd
Therefore length = w+4 = 7+4 = 11 yd
Area = length x width
Area = 11× 7
Area = 77 yd²

Answer:
(x+2)^{2} +5(x+2)-6=0
Let
u=(x+2)
Substitute in the expression
(u)^{2} +5(u)-6=0
therefore
the answer is
(u)^{2} +5(u)-6=0 is equivalent to (x+2)^{2} +5(x+2)-6=0
