It is
Answer:
B
Step-by-step explanation:
Note the common difference between consecutive terms of the sequence.
d = 16 - 12 = 20 - 16 = 4
This indicates the sequence is arithmetic with sum to n terms
=
[2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 4, thus
=
[ (2 × 12) + (41 × 4) ]
= 21( 24 + 164) = 21 × 188 = 3948 → B

Answer: 23
Step-by-step explanation:
62-39 = 23
Answer:
-15/41
Step-by-step explanation:
-3x + 15 - 6x = 30 + 32x
~Combine like terms
-9x + 15 = 30 + 32x
~Subtract 15 to both sides
-9x = 15 + 32x
~Subtract 32x to both sides
-41x = 15
~Divide -41 to both sides
x = -15/41
Best of Luck!
