Distributive property 1. 5(u − 5) 3. −5(e − 4) 5. 4(v − 6) 2. 17(2 + n) 4. −3(t + 7) 6. 4(a + 5) •Perimeter: The measurement of the outside of a shape •Area: The measure of the space inside of a shape Solving an Equation with Variables on Both Sides • 10 - 4x = -9x Write the equation. • +4x +4x Add 4x to each side. • 10 = -5x Simplify • 10 = -5x • -5 -5 Divide each side by -5 • -2 = x Simplify •Solve: 3(3x - 4) = 1/4(32x + 56) •Solve: 3(5x + 2) = 15x •A boat leaves New Orleans and travels upstream on the Mississippi River for 4 hours. The return trip takes only 2.8 hours because the boat travels 3 miles per hour faster downstream due to the current. How far does the boat travel upstream?
