The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol. So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.
Answer:
Step-by-step explanation:
Take some trinomial expansions to find some useful expressions and their values.
• 2nd degree expansion

• 3rd degree expansion

• 4th degree expansion

Simplify:



Then the equation we got from the 4th degree expansion reduces to

and all we need now is the value of
.
In the 3rd degree expansion, we have

So, we end up with

Answer:
The answer to your question is the first choicd
Formula for triangle perimeter is: a + b + c. In this scenario we have:
a = 3 feet 8 inches
b = 2 feet 10 inches
c = 4 feet
a + b + c =
= 3 ft + 8 in + 2 ft + 10 in + 4 ft =
= 9 ft + 18 in
We know that 1 foot is 12 inches, so we can simplify the result to this form:
10 ft + 6 in
or:
<u>10.5 feet</u>
