write two expressions for the perimeter of the figure. note: the figure is not drawn to scale. (a) use all three side lengths. perimeter = + + (b) simplify the expression from part (a). perimeter =

Answer

Explanation:

Step1: Write the perimeter using side - lengths

The perimeter of a triangle is the sum of its side - lengths. The side - lengths are 12, 8x, and 15x. So, perimeter = 12+8x + 15x.

Step2: Combine like terms

We have 8x and 15x as like terms. Combine them: 8x+15x = 23x. So, perimeter = 12 + 23x.

Answer:

(a) perimeter = 12+8x + 15x (b) perimeter = 12 + 23x
