Question

What’s the length of ac

Answer 1

Answer: 24

Step-by-step explanation: alright since AC = x+ 19, x+19 is equal to 2x+9+x. This means :

x+19 = 3x+9

subtract 19 from both sides:

x = 3x-10

now subtract 3x on both sides:

-2x = -10

Multiply by -1 on both sides:

2x = 10

x=5

Now we just add 19 to 5 to get 24
