A 17 ft ladder leans against the side of a house. The top of the ladder is 14ft off the ground. Find x, the angle of elevation of the ladder. Round your answer to the nearest tenth of a degree.

If a =6, what is the value of 2a(3b + 5c)?

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 =
