Given the diagram below, which pair of lines are skew?

To prove p is equal to q using an indirect proof what would your starting assumption be?

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 =

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)
