Any help with these problems would be greatly appreciated. I need all the help I can get.
1) Simplify (2x+3)(x-4)
2) Solve 7 x (-3) x (-2)^2

Solve 7 x (-3) x (-2)^2
Remember to follow the Order of Operations: PEMDAS.
So the exponentiation should be done first here, followed by the multiplications.
Remember that squaring a number is the same as multiplying it by itself. So when you square -2, you get (-2)(-2)=4.
Can you finish?
