Answer:
x = -2
TU = 4
UB = 2
Step-by-step explanation:
you can add x^2 with 4x+10 and equate it to 6:
x^2 + 4x + 10 = 6
x^2 + 4x + 4
then u can use the roots formula : x = (-b ± √ (b2 - 4ac) )/2a
so it'll be x = {-4±[√16 - 4(4)]}/2
x= -2
then u can substitute it and find TU and UB
TU= (-2)^2 = 4
UB= 4(-2)+10 = 2
Answer:
AC+CB=AB
Step-by-step explanation:
Let's see.... If you are a visual learner this could help.

So you can see that C is right in between them so the distance between AC and the distance between CB would equal the whole line AB. So if you add AC and CB you would get AB.
Answer:
Step-by-step explanation:
the formula for common difference is
d = aₙ - aₙ₋₁
So,
d = a₂-a₁ = a₃-a₂
d =7-14 & d=0-7
d = -7 & d = -7
