Answer:

19

Step-by-step explanation:

1a. r(-3)=-2(-3)^2+1=-17

2. We are left with q(-17).

2a. We plug -17 into where we x in q(x).

The sum of the first n consecutive even numbers can be found using S = n2 + n, where n ≥ 2.
viktelen [127]
The following are the choices on this question:
 A.6
 B. 39
 C. 26
 D. 12   
The answer is option D. 12.

Check this out:
S=n² + n
S= 12² + 12
     (you can get the square of 12 by multiplying 12 by itself: 12 × 12)
S=144 +12
S=156
