Answer:

A to C = 25

A to B = 13

C to B = 37

Step-by-Step Explanation:

Perimeter = 75

Sides:

2x + 3

3x + 4

2x - 9

1. Equal the sides added together to the perimeter

75 = 2x + 3 + 3x + 4 + 2x - 9

2. Simplify Like terms

2x + 3 + 3x + 4 + 2x - 9  = 7x - 2

3. Place the equation back together

75 = 7x - 2

4. Isolate the variables and numbers

75 = 7x - 2

+2        +2

77 = 7x

5. Simplify the equation

77 = 7x

/7     /7

11 = x

6. Substitute the value of x into the side lengths.

2x + 3 = 2(11) + 3 = 22 + 3 = 25

3x + 4 = 3(11) + 4 = 33 + 4 = 37

2x - 9 = 2(11) - 9 = 22 - 9 = 13
