15r^2 - 14r -12 is the correct answer
14 + 12 = 26
26 + 10 = 36
36 + 8 = 44
44 + 6 = 50
(notice the pattern)
14, 26, 36, 44, 50
Answer:
15m +31
Step-by-step explanation:
5(3m+7) - 4 = 15m + 35 - 4 = 15m +31
When a zero of a polynomial is "c", a factor is (x - c).
If the zero is p/q, a factor will be (x - p/q) or (qx - p).
The appropriate choice here is
d (x+1)(3x-2)(x-2)
