Write a linear expression in the simplest form to represent the perimeter of the triangle at the right. Then find the perimeter if the value of x is 10 millimeters

(7x + 8) + (6x + 6) + (9x - 4 )

230mm

Step-by-step explanation:

(7x + 8) + (6x + 6) + (9x - 4 ); x = 10

(7(10) + 8) + (6(10) + 6) + (9(10) -4)

(70 + 8) + (60 + 6) + (90 - 4)

78 + 66 + 86

230

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

its 8
