Answer:
12x^2-25x-7
Step-by-step explanation:
Multiply each term by its counterpart in the parenthesis.
4x*3x and 4x*-7
1*3x and 1*-7
This gives you 12x^2-4x*7+3x-7 when the like terms are combined.
Collect the like terms, which will give you 12x^2-25x-7
i believe the answer is 194

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
