How many different rectangular arrays can pablo make with all 36 tiles, so none of the arrays show the same factors?

Which expressions are equivalent to -6 + 3m

Which expression is equivalent to 8(k + m) − 15(2k + 5m)?

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
