When solving p^2 + 5 = 8p - 7. kate wrote p^2 + 12 = 8p. the property she used was:
1) the associative property
2) the commutative property
3) the distributive property
4) the addition property of equality

4)

Step-by-step explanation:

Because they just added the same equality. And when you move the -7 over the equal sign it makes it positive so it would be p^2 + 5 + 7 = 8p and that makes it p^2 + 12 = 8p
