The answer would be A. 21 because 21/7 would equal 3
Good for her what do you want me to answer
The reason for this has to do with finding the area of a square. When you are looking for the area of a square, you use the rectangle formula (since a square is also a rectangle).
The formula is Area = Length * Width
However, since in a square, the length and width are the same, both get changed to the word "Side". As a result, we get the following formula.
Area = Side * Side
This can be simplified to:
Area = Side^2.
Since each number to the second power also shows the area of a square with that given length sides, it can also be called "squared".
Answer:
m∠=6, ,m∠=+20,m∠=40+3
the larger the angle, the larger the side
Answer:
The base reduces at 3.75cm/min
Step-by-step explanation:
Given
Let



So:


The area of a triangle is:

Calculate b when 



Solve for b


We have:

Differentiate with respect to time

Substitute the following values in the above equation


Multiply both sides by 2


Collect like terms


Divide both sides by 8
