Answer:
x^2 + 11x + 18.
Step-by-step explanation:
The length = x + 9 and the width = x + 2.
So the area
= length * width
= (x + 9)(x + 2)
= x(x + 2) + 9(x + 2)
= x^2 + 2x + 9x + 18
= x^2 + 11x + 18.
sub equation 1 into 2
2-5x=x²-2x-8
0=x²-2x+5x-8-2
0=x²+3x-10
0=(x-2)(x+5)
x=2 or x=-5
sub x into equation 1
y=2-5(2) or y=2-5(-5)
y=-8 y=27
The solution is (3,-5)
