Answer:
The answer should be 3 cubic cm
Step-by-step explanation:
First you have to get the area of the right triangle base 1/2 bh. That would be 2x3/2=3
To find volume, you plug the area in the volume formula
v=1/3 ah
v=1/3 (3)(3)
1/3(9) would be 3 cubic cm

Answer: x=12, x=-3
Step-by-step explanation: For this factored problem, you see that -36 is negative, as well at -9. This shows you that you need to find two numbers that multiply to get -36, and add up to get -9. Two numbers that both satisfy these requirements are -12 and 3. They multiply to get -36, and add to get -9.
Once you have found your values, you plug them into (x+/- __)(x+/- __), which is (x-12)(x+3).
But since the problem asks you to find the zeroes, you set each factor equal to zero, like this:
x-12=0 and x+3=0
Then solve and you have you answer!
