Question

4) What is the measurement of each side if the perimeter is 94?
2a+ 1
3a + 2
5a-9

Answer 1

Measurements are:

BA= 21

AC= 41

BC= 32

Explanation:

the sum of all of the sides is 94 so therefore 2a + 1 + 3a + 2 + 5a - 9 = 94

from there you can combine like terms which would give you: 10a - 6 = 94

then you solve for a. a = 10, so if you replace a with 10 in every equation you get the measurements of the sides:

2(10) + 1 = 21

3(10) + 2 = 32

5(10) - 9 = 41
