Answer 1

Answer:

BC=25

Step-by-step explanation:

this is an isosceles  triangle, so sides AB and sides AC are equal

AB = AC

4x+1 = 2x+23

subtract 2x from each side

2x+1 = 23

subtract 1 from each side

2x =22

divide by 2 on each side

x =11

BC = 3x-8

substitute the value of x

BC = 3*11 -8

BC = 33 -8

BC=25

Answer 2

Answer:

The answer would be - BC is 25

Step-by-step explanation:

• Sides ab and ac are equal

• 4 x + 1 = 2x +23
• then after that you subtract 2 times from every side
• 2x + 1 = 23
• Then 1 more time from every side
• 2x =22
• Then divide by 2 on each side of the Triangle
• x =11
• BC = 3x -8
• After you do all of this then you would sub. the  value of x
• So BC = 3*11 -> 33 -8
