The answer is C. A way to find out is to add a few numbers from that group being specified. If you add 2 or even 100 to 3, the answer will be odd. If you add 12 to 3, you will get 15 which is a composite number. If you were to add 2 to 3, you will get 5 which is an odd number.
Exponential
The first year, he would earn 8% interest on the $400 deposited, so he'd have $432. The next year, he would earn 8% interest on the interest earned the previous year in addition to the amount deposited, so he'd have $466.56.
His bank balance would follow the compound interest equation which is exponential.
= 400 × 1.08^t
where t is the number of years since the deposit
Step-by-step explanation:
w(2w - 30) = 5400
2w²- 30w = 5400
2w² - 30w - 5400 = 0
(w - 60 ) ( w + 45 ) = 0
w= 60 w= - 45
only take the positive value
therefore w = 60
Answer : 118 or -40
