What is 24a + 9
Like Terms OR NOT Like Terms 3x + 2y + 2xy
Not like terms
-7w - 5 + 17w + 15
What is 10w + 10
Distribute 2(x+4)
2x+6

In the problem 3(2+5) show that you can solve the problem by using order of operations, OR by distributive property and you will get the same answer either way.
3(7) = 21 3(2) + 3(5) = 6+15= 21
