2.7 + 1.7i
We require the fractions to have a common denominator.
multiply the numerator of the first fraction by (3 - i) and the numerator of the second fraction by (3 + 1)
=
=
[ note that i² = ( = - 1]
= = 2.7 + 1.7i ← in standard form

You add the fractions.
turn it into an improper fraction. you multiply the whole number by the denominator then add the numerator, leaving it over the original denominator.
eg/ 2×4= 8 +3 = 11/4
1×2= 2 +1 = 3/4
find a common denominator.
eg/ 2 and 4 have the common denominator of 4.
then you make the denominators the same.
eg/ 3/2 × 2 = 6/4
add them.
eg/ 11/4 + 6/4 = 17/4
lowest terms.
eg/ 4 1/4

which means -3=7(1)-10
<u>Answer-</u>
<em>The maximum area that they can fence off is</em><em> 6400 ft²</em>
<u>Solution-</u>
Organizers of an outdoor concert will use 320 feet of fencing to fence off a rectangular vip section.
i.e the perimeter of the rectangular section is 320 feet
Let us assume,
x = length of the rectangular section
y = breadth of the rectangular section
Hence,
Now, we have to find the maximum area for which they can fence that off.
The area of the rectangular section is,
So we have to maximize the area function.
Putting the value of y,
Finding the critical values,
∵ f"(x) is negative (i.e -2), so for the value of x=80, f(x) or area function will be maximum.
Therefore, the maximum area that they can fence off is 6400 ft²
