the 20x(8+2) is just two times greater as its 200 instead of 100 which is the other answer
X=12.5
If the perimeter is 90
90=3x+3x+15
Combine like terms
90=6x+15
Subtracts 15 from both sides
75=6x
Divide by six to get x by itself
12.5=x

Answer:
y=25
Step-by-step explanation:
y=4+4x+x^2

y=4+12+(3x3)
y=4+12+(9)
y=16+9
y=25
