Answer:
4x^3 - 15x^2 - 10x + 24
Step-by-step explanation:
FOIL (x-4)(4x^2+x-6)
= x(4x^2+x-6) -4(4x^2+x-6)
= 4x^3+x^2-6x-16x^2-4x+24
=4x^3-15x^2-10x+24
BFC makes this angle add up to 90 degree at BFD
Therefore it becomes complementary to angle CFD
Approx: 2.65units
C. Because (-3)^2 is NOT equal to -9
