Answer:
M = 7
Step-by-step explanation:
6m + 2(6 + 7m) = -128
6m + 12 + 14m = -128
20m + 12 = -128
Subtract 12 both sides
20m = 140
Divide by 20 both sides
M=7
Answer:
divide both side of inequality by 4 but don't flip the symbol
Answer:
none of them are correct
Step-by-step explanation:
You could factor a 7 out of 7 + 14 to get 7(1 + 2).
This would equal the same thing as 7 + 14, which is 21.
7 * 3 = 21.
21 can be factored like so:
1 * 21 = 21
3 * 7 = 21
To do this problem you would need to have at least one side length AND the hypotenuse to figure out the other side length.
