Answer:
9 units
Step-by-step explanation:
To find the length of a side of a square, you need to square root the area
√81 = 9
This really is left up to you as long as you have an odd number in the tens place and a 7 in the ones place. How big (or small) the number is is up to you. As long as it is at least 17, it's pretty much up to you.
23 below zero means you will actually subtract (remove) 23 from zero.
This can be represented using the following expression:
0 - 23
To represent this as an integer, this means you will use a negative sign to represent the removal or subtraction of the number followed by the number removed which is 23, therefore:
The integer to represent this is -23.
So the answer would be x=1 and y=-2. Hope this helps
Sqrt(56x^2) = x*sqrt(56) = x*sqrt(4*14) = x* sqrt(4) * sqrt(14)
= 2x*sqrt(14) (answer)
