Answer:
im pretty sure all you have to do is switch the signs (if its negative it will become positive) but only for the points on the x axis so basically (-12,13) would become (12,13)
Answer:
800 cm^3
Step-by-step explanation:
An easy way is to cut the base up into two parts. Take a look at the drawing I added below for explanations!
Rectangle ACDG has an area of 28.
--> (12-5)(4) = (7)(4) = 28
Rectangle BFEG has an area of 72.
--> (10-4)(12) = (6)(12) = 72
So the total area of the base is 28 + 72 which is 100.
Base x Height is the volume, so it will be 100 x 8 (The height) = 800
So 800 cm^3 is your answer!
Answer: I think the last option is the correct answer.
