6m + 5 = 3m - 4Subtract 3m from each side:3m + 5 = -4Subtract 5 from each side:3m = -9Divide each side by 3:m = -3

3m-5 = 7-21 3m = 7-21+5 3m = -9 m = -3

Perimeter = 33+33+3+3 = 72 m

m = 3

m=5

P = 33m + 33m + 3m + 3m = 69 meters

6m + 5 = 3m - 4Subtract 3m from each side:3m + 5 = -4Subtract 5 from each side:3m = -9Divide each side by 3:m = -3

The perimeter of a triangle is the sum of its three sides. If two are 3m and 2m then their sum is 3m + 2m = 5m And the remaining side can be calculated by taking this sum from the perimeter → the other side is 9m - 5m = 4m long.

3m-5 = 7-21 3m = 7-21+5 3m = -9 m = -3

If 3m - 7 = 8, then m = 5

3m+2=17 First, subtract 2 to get m on one side. 3m+2-2=17-2 3m=15 Divide by 3 to get m by itself. 3m/3=15/3 m=5 m equals 5.

Perimeter = 33+33+3+3 = 72 m

mn - 15 + 3m - 5n Rearranging: mn + 3m - 5n - 15 = m(n + 3) - 5(n + 3) = (m - 5)*(n + 3)

It is: 4m+5

The value of m in the equation: 4m-5 = 3m +7 is 12.

m = 3

m=5
