The first side of a triangle measures 3 in. less than the second side, the third side is 2 in. more than the first side, and the
perimeter is 20 in. Set up an equation that relates the sides of the triangles in terms of the perimeter of the triangle.

Answer:
P = 3x - 4
Step-by-step explanation:
Side 1 = x - 3
Side 2 = x
Side 3 = 2 + (Side 1) = 2 + x - 3 = x - 1
Perimeter = 20 in
Perimeter = Side 1 + Side 2 + Side 3
Perimeter = (x - 3) + (x) + (x - 1)
Perimeter = x - 3 + x + x - 1
Perimeter = 3x - 3 - 1
Perimeter = 3x - 3 - 1
Perimeter = 3x - 4
P = 3x - 4

Answer:
Find two good points and do rise over run. or you can do the x1 y1 thing
Step-by-step explanation:
5x and -8x are like terms. 6 is not a variable. 5 is the coefficient of the term 5x. X is not the constant.
First find out what 10 percent of 50 is
Do 50/10
I got 5
Then do 5 times 9 to get your answer
You should get 45. Thanks (:
