Answer:
BC = 26
Step-by-step explanation:
since B is the midpoint of AC, then AB = BC
AC = 8x - 20 & AB = 3x - 1
AC = AB + BC or 2AB
8x - 20 = 2(3x - 1)
8x - 20 = 6x - 2
subtract 6x form each side
2x - 20 = -2
add 20 to each side
2x - 20 + 20 = -2 + 20
2x = 18
x = 9
BC = 3x - 1
BC = 27 - 1
BC = 26
AC = 52

The standard form of equation is: 4x+2y = -13
Step-by-step explanation:
the standard form of a linear equation in two variables is given by:
![ax+by = c](https://tex.z-dn.net/?f=ax%2Bby%20%3D%20c)
Given equation is:
![2y+5=-4(x+2)](https://tex.z-dn.net/?f=2y%2B5%3D-4%28x%2B2%29)
Distributing -4 into the round bracket
![2y+5 = -4x-8](https://tex.z-dn.net/?f=2y%2B5%20%3D%20-4x-8)
Adding 4x on both sides
![4x+2y+5 = -4x-8+4x\\4x+2y+5 = -8](https://tex.z-dn.net/?f=4x%2B2y%2B5%20%3D%20-4x-8%2B4x%5C%5C4x%2B2y%2B5%20%3D%20-8)
subtracting 5 from both sides
![4x+2y+5-5 = -8-5\\4x+2y = -13](https://tex.z-dn.net/?f=4x%2B2y%2B5-5%20%3D%20-8-5%5C%5C4x%2B2y%20%3D%20-13)
The standard form of equation is: 4x+2y = -13
