Answer:
see explanation
Step-by-step explanation:
Calculate AC and AB using the distance formula
d =
with (x₁, y₁ ) = A(1,8) and (x₂, y₂ ) = C(4,2)
AC =
=
=
= = = 3
Repeat with
(x₁, y₁ ) = A(1, 8) and (x₂, y₂ ) = B(2, 6)
AB =
=
=
=
So AB = and AC = 3
Thus
AC = 3AB
Answer:
3
Step-by-step explanation:
The highest degree amount or exponet amount is the power of a equation.
3 is the highest exponet so it is 3.
4.5, 5/2=2.5 7/2=3.5 so the answer is 4.5
Answer:
Step-by-step explanation:
D^2 + 17d + 72 = 0
( d + 8 ) ( d + 9 ) = 0
d = - 8 , d = - 9
