Explanation:
17:
it is saying <em>a+b=b+a</em> so put 5+16 that would be commutative
18:
if asking to rewrite it using the distributive prop do 20(2+x) that would still be distributive,
if asking to solve it is 40+2x
19: if I understand correctly it is asking you do write it using the associative property, if so do 4 * (60)
20: Do it as so, 6(x + 15) where x is your number
21: (x+5) + 27
22: 7(x+4) + 2x Simplify as so. Distribute, then add like terms (X)
7x + 28 + 2x
9X + 28
23: 6x + 15 - x + 4 Simplify : add and subtract like terms. (x) (#'s)
5x + 19.
24: 22y + 3x- 7y Simplify: Subtract like terms (y)
15y + 3x
