Ijust need for 3 questions! write an expression for the perimeter of the triangle shown below: a triangle is shown with side lengths labeled 2.3x plus 14, 2x, and negative 0.2x plus 15. 4.1x + 29 4.1x − 29 4.5x + 29 4.5x − 29 which expression is equivalent to 1/5m − 20? 1/5(m − 4) 1/5(m − 100) 5(m − 4) 5(m − 100) write an expression that is equivalent to 3/5 (3y + 15). three over fivey + 9 three over five y + 15 nine over fivey + 9 nine over fivey + 15
