the perimeter is 35 and are is 40
172.9
You find it by multiplying each side of the triangle by the height (9) and adding the results together.
A(lateral) = 8 * 9.1 + 3 * 9.1 + 8 * 9.1
= 72.8 + 27.3 + 72.8
= 172.9
This is a simply problem. Just divide both sides the coefficient of x. Which is -2.
And the answer will be x = -4
