Answer:
7m^2 - 11m - 2
Step-by-step explanation:
Subtract (-3m^2 + 10m + 4) from 4m^2 - m + 2:
   4m^2 - m + 2
- (-3m^2 + 10m + 4)   Now distribute the negative sign:
   4m^2 - m + 2
+ 3m^2 - 10m - 4
--------------------------
    7m^2 - 11m - 2 is the final answer.

Answer:
772.4 ft^2
Step-by-step explanation:
find the area of each face. first the slanted rectangle. the dimensions of the slanted rectangle are 21.7ft by 12ft. so the area is 21.7*12=260.4ft^2. for the two triangles on the sides, each on has an area of 20*8.5/2=85. next for the smaller rectangle, the dimensions are 12ft by 8.5ft giving us an area of 102 ft^2. lastly for the base, it has dimensions of 20ft by 12ft giving us an area of 240ft^2. now you just add up all the areas: 260.4+85+85+102+240=772.4 (you might want to check my addition just in case)
