Question

In triangle ABC show find BC.. Need help ASAP!!!

Answer 1

Answer:

Segment BC is (3d + 7)cm, where d=5. So, BC= 22cm.

Step-by-step explanation:

Segment BC is (3d + 7)cm, where d=5. You find this through these steps:

(5d-3)=(3d+7)           Subtract 3d from 5d, which equals 2d.

2d-3=7                     Now, add 3 to 7.

2d=10                       Divide 10 by 2.

d=5                          The solution is 5.

Plug 5 into the equation of Segment BC:

3(5) + 7

BC= 22

Answer 2

Answer: BC=22cm

Step-by-step explanation:

5d-3=3d+7

2d=10

d=5

plug 5 into the equation for BC, and you get 22
