Hope the answer I gave you helps!!!

I mean, I don't know how to explain a generic way to solve this. Ask me about the specific train of thought if you are interested:
7 * 18 + 45 / 3 - 2 = 139
The Distributive Property Is Used When You Multiply 3x To (5-2) Which Then Means
15x-6x= 15-6
9x=9
Divide Both Sides By 9
x=1
11 and 12
since 11*11 equals 121 and 12* 12 is 144
It's technically in it's simplified form unless you want the decimal of 1.727 (1.73)
