4(5a + 3) = 20a + 12 represent which property of multiplication?

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 =

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.
