Option 3 is the correct one
Answer:
let's see what to do buddy...
Step-by-step explanation:
" First four terms " means :
t(1) , t(2) , t(3) , t(4)
So the first four terms
are : 4 , 9 , 14 , 19
If he earns 30,000 annually, he will make about 2,500 a month, biweekly 1,250,
and his weekly pay would be an estimated $625
Plug in "8i + 15j + k" for "f", and "2i – 5j + 9k" for "e"
3(8i + 15j + k) - 2(2i – 5j + 9k)
Distribute 3 to (8i + 15j + k) & - 2 to (2i – 5j + 9k)
3(8i + 15j + k) = 24i + 45j + 3k
-2(2i - 5j + 9k) = -4i + 10j - 18k
-------------------------------------------------------------------------------------------------------------------
Simplify. Combine like terms
24i - 4i + 45j + 10j + 3k - 18k
(24i - 4i) + (45j + 10j) + (3k - 18k)
20i + 55j - 15k is your answer, or (C)

hope this helps
