Answer:
f(6) = -114
Step-by-step explanation:
f(x) = -4x² + 5x
f(6) = -4(6)² + 5(6)
f(6) = -4(36) + 30
f(6) = -114 + 30
f(6) = -114

Step-by-step explanation:
Hope it helps, tell if not.
x +1 x^2 +5x +4 x +1 (x +1)(x +4)
---------------- / ---------------------- = ----------------- / ----------------------- =
x^2 +x -6 x +4 (x +3)(x -2) x +4
x +1 1 1
= ---------------- * ----------- = ------------------
(x +3)(x -2) ( x +1) (x +3)(x -2)
so the second choice is right sure

Answer:
x = 8
Step-by-step explanation:
Since B is between AC , then
AB + BC = AC , that is
2x + 1 + 3x = 41
5x + 1 = 41 ( subtract 1 from both sides )
5x = 40 ( divide both sides by 5 )
x = 8
