Determine whether the given value makes the open
sentence
true.

92 –2m≤7+3m, when m =12

14-3n ≥ 8 + 2n when n = -5

8 + |y| -x=y+ |3x|,when x=-4 and y=9

simplify the expressions by combining like terms.

4a ² + 7b ² + 5b ² - 2a

3x + 8x ² - 4x + 15

match the example with the correct property

(12 x 7) x 5 = 12 x (7 x 5) commutative property

9(x + 4) = 9∙x + 9·4 associative property

3 + 4 + 8 = 4 + 3 + 8 distributive property

if x = y, then y = x symmetric property
