Hey there!
The answer to your question is 
Given:

First, we distribute the negative sign to both terms (
) This would make the
negative and the
positive, so we have:

Add them together and we get:

Have a nice day!
Answer:
Width=20 feet
Since Length=Width=20 feet, the rectangle is a Square.
Step-by-step explanation:
Area, 
To determine the width of the rectangle that gives the maximum area, we take the derivative of A and solve for its critical point.

The width of the rectangle that gives the maximum area =20 feet.
Perimeter of a rectangle=2(l+w)
Perimeter of the rectangle=80 feet
2(l+w)=80
2l+2(20)=80
2l=80-40
2l=40
l=20 feet
Since the length and width are equal, the special type of rectangle that produces this maximum area is a Square.
Answer:
6/5 or 1 1/5
6/5 is an improper fraction, so I didnt know if youd need an improper one or a proper one. They both are the same thing though :)
Step-by-step explanation:
4/10*3
They both need to be a fraction, and any number over 1 = that number. So,
4/10*3/1
4*3=12
10*1=10
12/10
Then, you have to simplify the fraction.
6/5 (bc 2 goes into 12 6 times and 2 goes into 10 5 times)
or 1 2/10= 1 1/5
Hope this helps. Plz give brainliest. Also, plz sub to Kgirl633 on yt.
Answer:
5
Step-by-step explanation: BECAUSE IN A PARALLELOGRAM OPPPOSITE SIDES ARE EQUAL SO IF THE PERIMETER IS 33.2 WE SHOULD SUBTRACT THAT NUMBER WITH 11.6*2 WHICH IS 23.2 SO 33.2-23.2 WHICH IS 10,SO 10/2 IS THE OTHER SIDE OF THE PARALLELOGRAMWHICH IS NOTHING BUT 5
