Question

If AC =65, AB = 6c- 8 BC= 3c+1
​

Answer 1

Answer:c=8

Explanation:

AB + BC = AC

6c-8 + 3c+1 =65 (simplify)

9c -7 =65 (combine like terms) (cancel out the -7 by adding 7 to both sides).

9c = 72 (Divide both sides by 9 to get c by itself.

c=8

Then substitute c for 8

AB = 6(8)-8 = 40

BC = 3(8)+1 = 25

AC = 40 + 25 =65
