B C = 24
Explanation:
The triangle is isosceles, because (from the diagram) ∠ A B C = ∠ A C B - note how the angle there is marked on both of these. If these angles are equal, this means that the sides
A C = A B
let A C = A B
x +8=2x-1
8 = x − 1
x = 9
We want to find the length of
B C , which is ( 3 x − 3 ) . We know that x = 9
B C =3 x − 3
B C = 3 ( 9 ) −3
B C = 27 − 3
4x-2=8
4x=86-2
4x=84
4x/4=84/4
x=84/4
x=21

f(4) = -1
f(4) = 3(4)^2 - 10(4) -9
= 3*16 - 40 - 9
= 48 - 40 - 9
= -1
