Jamal bought 2 packs of stickers and 8 individual stickers. use x to represent the number of stickers in a pack of stickers and write an expression to represent the number of stickers jamal bought. is the expression equivalent to 2(4+x)? check your answer with algebra tile models.

Which matrix multiplication is possible?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
