In any trapezoid, the area is given by

where B and b are the two bases, and h is the height. You're given all these elements already, so you only need to plug the values in:

Answer:
-7
Step-by-step explanation:
-4(2)=-8
-8+1=-7........
The answer is a because its 125 divided by 4
D = M/V ( Density equals mass divided by volume )
This problem is very simple. Knowing that y=2, plug 2 into the "y" in the equation: -x+2(2)=8
-x+4=8
subtract 4 on both sides of the equation:
-x=(8-4)
-x=4
Divide both sides of the equation by (-1):
x=(-4)
