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
