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
