Number that produces a specified quantity when multiplied by itself
Example : “ 7 is a square root of 49 “ BECAUSE 7x7=49
I think that the best answer here would be that A = 40 degrees.
(5•4)-8 the answer is 12 because 5 times 4 is 20. Then 20 minus 8 is 12.
Yes that’s completely true because of course you can’t say it is false
We know that the perimeter is the all the sides added up together. Generally, you have

, where l is length and w is width.
For a square, all sides are of the same length, so you can write

, where x is any side.
If the smallest perimeter is 14, then

, so x is 3.5. If the largest perimeter is 72, then

, so x is 18.
Therefore, you have 3.5 ≤ x ≤ 18.
