-7m - 3m + 5m = -5m
what is 7m+7-5m
Gather the m's and n's by rewriting it. 7m - 11n - n + 5m 7m + 5m -11n - n (7m + 5m) + (-11n - n) 12m - 12n ■
5m-7m = 12 -2m = 12 -2m/-2 = 12/-2 m = -6

5m-12n
-(4m + 3)(5m - 2)
I think there is a missing operator in your question; I will guess you mean 5m + 7m - 3 = 33, because that has a nice round answer. First, add 3 to each side: 5m + 7m = 36 Then, simplify the left side: 12m = 36 Finally, divide both sides by 12: m = 3

there is 7m people in the so 5m play cod
m = 8
Just multiply 5m x 7m. The depth won't change the area of the top surface. Now, if you have a block and want to have its total surface area, calculate the area of the six bounding rectangles, and add them: two times 5x7, two times 5x1.6, two times 7x1.6.
