We need some definitions for this one :). Let's start by defining a square.
A square is a special rectangle with all sides equal to each other.
Now let's do the algebra.
The area of a 4 x 16 rectangle would be 64units².
Now all we need to do is find the square root of 64. If you don't know, finding the square root of a number basically means finding a number that when multiplied by itself equals 64. Which number times itself equals 64? Your answer is 8!
We needed to find the square root because we know that it would not be a square unless all sides are the same length.
Hope this makes sense. Good luck!
Answer:
4x + 4
Step-by-step explanation:
That's what I did and since the zeros would be -5 and 3 the answer would be 3 since it can't be a negative
Check the picture below.
the quadrilateral is a parallelogram, thus the diagonals bisect each other, so, we could have used either diagonal, and get the same midpoint.
