Get 10 points to answer this!! If x + y = 0, then x and y are a) Equal b) Additive inverse to each other c) Multiplicative inverse to each other d) Maybe any of these

Step-by-step explanation:

If x + y = 0, then x = -y

Hence they are additive inverse to each other. (b)

1) 2x * 2x = 4x^2

2) 2(-1)+6 = 4

3) (4x)(6x+6) = 24x^2 + 4x

4) ((6)+4)(5(6)) = 300

5) 4x(x+1)= 4x^2+4x

6) (-x-3)(-5x+10) = 5x^2+5x-30

7) (2(4)+3)(5(4)-2) = 198

8) ((5)^2+2)(2(5)-1)=243

9)
