Answer 1

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.
