Answer:
the square root of 20 could be between 4 and 5 OR -4 and -5.
Step-by-step explanation:
plus or minus 4 squared is 16 and plus or minus 5 squared is 25. finally, 20 is between 16 and 25.
The equation is

If you put in the numbers you get

This comes to 1056. So the answer is 1056 in^2
the answer is x is greater then -7
to find this add 4 to each side
then divide by -2.
since you divided both sides by a negative the symbol flips and you get x is greater then -7
<span>22% when expressed as a fraction is 22/100.
to write this in the simplest form, we have to keep dividing both numerator and denominator by a common number.
22/100 , both are divisible by 2. therefore when 22/100 is divided by 2

then we get 11/50. this cannot be divided any further by a common factor to both. therefore simplest form is 11/50</span>
