Simple..
For area, it's A=l*w
15*2=30
And, perimeter, it's P=l+l+w+w
15+15+2+2=34
Thus, your answer.
l=15 and w=2,or, w=15 and l=2
Step-by-step explanation:
here ! I used the formula area = length × width
and just some algrbric expressions solving
divide both sides by 7 to get x alone
84/7 = 12
B.12
Answer:
8 years.
Step-by-step explanation:
The simple interest formula is principal × rate (as a decimal) × time = interest. In this question, you want to find the time.
First, plug in your numbers. 350 × .055 × t = 154. Then, to find t, divide to get t one side.
t = 154 / 350 × .055
Then solve.
350 × .055 is 19.25. 154 / 19.25 is 8.
So, your answer is 8 years.
154/350*.055 = t
