The formula for the area of a trapezoid is a=1/2(b1+b2)h
So 10*5 = 50 *4 = 200 then divided by 2 is 100 so the answer is 100
Answer:
B
Step-by-step explanation:

(Subtract 2L from both sides of the equation)
(Symmetric Property of Equality)
(Divide both sides of the equation by 2)
("Split" the fractions)
(Simplify)
Hope this helps!
(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
The answer would be (x+1) and (x+10) so E
