Answer:
Your handwriting is really nice! Here is what I have so far:
Step-by-step explanation:
1. x + y
A: (2) + (4) = 6
2. (Don't remember how to do this one.)
3. 2x - 7
A: 2(-1) - 7 = -9
4. 7x^2 - 12x + 13
A: 7(16) - 12(4) + 13 = 112 - 48 + 13 = 77
5. -3p^2 + 4p + 7
A: -3(4) + 4(-2) + 7 = -12 -8 + 7 = -13
6. 3a -(a+2b)
A: 3(1) -([1] + 2[-1]) = 3 + (-1 + 2) = 3 + 1 = 4
7. (I can not see the value of Y.)
8. (I can't understand the equation. Please type it out for me in the comments.)
I need clarification for a few before I continue.
