Answer:
Step-by-step explanation:
A) Using the foil method and distribution, you should get x²+10x+7x+70 from (X×X)+(X×10)+(X×7)+(7×10). When you combine these like terms, you get x²+17x+70.
B) Using the same ideology from part A, when you multiply x-3 into x-9. you should get x²-9x-3x+27. Simplifying this will give you x²-12x+27.

Answer:
b. 82m³
Step-by-step explanation:

Answer:
Well first you put the y-intercept on the graph. In this case it would be 15
So graph the point (0,15)
The you do the slope which is 3
so you always do rise over run for slope.
If 3 were a fraction it would be 3/1 so go up 3 points and the go right 1 point from (0,15)
hope this helps .-.
It would be...
(18 +28) divided by two
then take that and multiply it by the height - 5
the 6 in this equation doesn't matter because it is not the height of the shape
