Question 565900
Area of triangle = 1/2 L*H

base of X + 6, the height is X + 8

1/2(x+8)(x+6)= 60

1/2(x^2+14x+48)=60

multiply equation by 2

x^2+14x+48=120

x^2+14x+48-120=0

x^2+14x-72=0

x^2+18x-4x-72=0

x(x+18)-4(x+18)=0

(x+18)(x-4)=0
x=-18 OR 4

ignore negative because the length and height cant be negative

x=4
plug x=4
base = x+6 = 10 units
height = x+8 = 12 units

CHECK

1/2 * 10*12= 60
