A: Perimeter = 2*length + 2*width = 2x^2 + 14x + 4
B: Area = length*width = 4x^3 + 12x^2 + 8x

No one and his is for homework help only
Eliminate 'y' by equating
<span>8x - 40 = x^2 - 2x - 15 </span>
<span>x^2 - 2x - 8x - 15 + 40 = 0 </span>
<span>x^2 - 10x + 25 = 0 </span>
<span>(x - 5)(x - 5) = 0 </span>
<span>(x - 5)^2 </span>
<span>Hence x = 5 is the only solution for 'x'. </span>
<span>Substitute in to the linear eq;n for 'y' </span>
<span>y = 8(5) - 40 </span>
<span>y = 40 - 40 </span>
<span>y = 0 </span>
<span>Hence the solution in ( x,y) form is ( 5,0).
