I believe the answer is....
For solving for a
a-7= 3(b+2) ———> distribute 3(b+2)
a-7= 3b+6 ———-> add 7 on both sides
a-7= 3b+6
a+7= 3b +7 ———-> the 7’s cancel out so you’re left with....
a = 3b + 13 (That’s your answer)
Hope that helped :3
Surface area of a cube is n^2, n being the measurment of any one side of the cube. In this case, 13x13=169, so the answer is 169 mL^2.
