Answer 1

in the given question,
BC is the given side

Answer 2

Thank you for asking this question. Here is your answer:

4x+4 = 6x-14

4x + 4 + 14 = 6x - 14 + 14 (we added 14 on the both sides so that we can get x alone on the right side)

4x + 18 = 6x

4x + 18 - 4x = 6x - 4x

18 = 2x

18/2 = 2x/2

x = 9

2x+7

2(9)+7

18+7= 25

So that means BC equals to 25
