Answer:
59.5
Step-by-step explanation:
area of the triangle is (7 x 3)/2=21/2=10.5
area of the square 7x7=49
Steps to solve:
-3(x + 2) = 12
~Distributive Property
(-3 * x) + (-3 * 2) = 12
~Simplify
-3x - 6 = 12
~Add 6 to both sides
-3x - 6 + 6 = 12 + 6
-3x = 18
~Divide -3 to both sides
-3x/-3 = 18/-3
x = -6
Best of Luck!
