Answer:
7 ft
Step-by-step explanation:
Perimeter of a rectangle is denoted by the formula: 
, where l is the length and w is the width.
We know that P = 20 and that w = 3. So, let's plug these values in:
Isolate the variable 
by subtracting 6 from both sides and dividing by 2:
Thus, the answer is 7 feet.
Hope this helps!
Answer:
16^25
Step-by-step explanation:
The applicable relation is ...
(a^b)^c = a^(bc)
2^100 = 16^x = (2^4)^x = 2^(4x)
Equating exponents, we have ...
100 = 4x
25 = x
Then 2^100 = 16^25.
"Simple interest" means the interest goes into a separate bucket, and
it just waits there for you to come and get it. It <em><u>doesn't</u></em> get added to the
amount in the account, so next year, you don't get interest on the interest.
4 percent of $2000 is (0.04 x 2000) = $80 .
That's how much interest you get each year.
At the end of 4 years, you have (4 x $80) = <u>$320</u> in the interest bucket.
(And of course, you still have the original $2000 in the account.)
