The answer is B. -7m+12.


First distribute the -2 to 6m and -5.

5m-2(6m-5)+2

5m+(-2*6m)+(-2*-5)+2

5m+-12m+10+2


After that, combine the like terms.

5m+-12m+10+2

-5m+-12m=-7m

10+2=12


The simplified expression is -7m+12.

Answer:

105

Step-by-step explanation:

Area of a trapezoid is given by the formula:

A = (a+b)÷2×h

(where h is the vertical height, and a and b are the parallel lines)

Substituting values given gives us:

A = (6+15)÷2×10

A = 21÷2×10

A = 10.5×10

A = 105

Units will be m² as this is area.
