Answer:

I believe that the answer is 1

Step-by-step explanation:

So an identity is an equation that both sides are equal.  So in the first answer 3(5 +2x)=15+6x  equals each other because after distributing the 3 into the (5+2X) it equals 15+6x

Answer:

A

Step-by-step explanation:

3(5 + 2x) = 15 + 6x

15 + 6x = 15 + 6x

6x - 6x = 15 - 15

0 = 0

No solution, no identity.

y = x + 3

No identity.

Identity : a² - b² = (a + b) (a - b)

The only identity is option 3.
