Please help again! Asap
I'm not good at this math :(

Answer 1

BC = 9

Explanation:

First, you need to find what x is and then plug it into the equation for BC.

You can do this by setting both equations equal to 26, which is the total length.

9x+8+7x+2=26

16x=16

x=1

Now that we know x is 1, plug it into BC:

BC = 7(1)+2

BC = 7+2

BC = 9

Answer 2

BC=9

Explanation:

AC=AB+BC

26=9x+8+7x+2

16x+10=26

16x=16

x=1

BC = 7*1+2=7+2=9
