Answer:
C) x²-2x-15=0
Step-by-step explanation:
You could put both -3 and 5 in the equations to guess and check, but the better way is to use them to create the factors. If -3 is a root, one of the factors must be (x+3). If 5 is a root, the other factor must be (x-5).
(x+3)(x-5)
x²-5x+3x-15=0
x²-2x-15=0
55.79 = 0.99<em>d + </em>39.95
55.79 - 39.95 = 15.84
0.99d = 15.84
0.99d/0.99 = 15.84/0.99
d = 16
2) Equation = 12.6 million = 4(x) + 1 million
12.6 million - 1 million = 11.6 million
11.6 million/4 = x
x = 2900000

Answer:
3x^2-x+5.2f\left(-3\right)-f\left(4\right) =
3x^2-x-19.6f
Step-by-step explanation:
3x^2-x+5.2f\left(-3\right)-f\left(4\right)
=3x^2-x-5.2f\cdot \:3-f\cdot \:4
=3x^2-x-15.6f-4f
=3x^2-x-19.6f
