Answer: See explanation
Step-by-step explanation:
15.) -7x + 6 (x - 8/2) - 2(x + 3) + 10
-7x + 6 (x - 4) - 2(x + 3) + 10
-7x + 6x - 24 - 2x - 6 + 10
Bring like terms together
-7x + 6x - 2x - 24 - 6 + 10
-3x - 20
16.) B, C, D
B. 3 (x + 2) + 4x
3x + 6 + 4x = 7x + 6
C. -2 + 4(x + 3)
-2 + 4x + 12 = 4x + 10
D. 3x + 5(x - 1)
3x + 5x - 5
8x - 5
17.) A, B, D
A. 1/5(x - 50)
1/5x - 10
B. 1/6(-x + 12)
-1/6x + 2
D. 1/2(x + 16)
1/2x + 8
Remark
I don't know exactly what level you are in, but the obvious factors are
y = 2x*(x^3 + 11x + 30)
This gives one more factor somewhere around x = -11.3 . Notice that the minimum is around - 3000 or so. I don't think anyone is going to try and take this any further. My calculator figures out cubics and gives an answer of -11.23. There are two other roots but they are a complex pair.
Answer
factor 1: 2x
factor 2: x^3 + 11x^2 + 30
Answer:
A. -10
B. -1
C. 5
Step-by-step explanation:
A. 3x-4 = 3(-2)-4 = -10
B. 3x-4 = 3(1)-4 = -1
C. 3x-4 = 3(3)-4 = 5
