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
