Answer:
length = 15 feet.
Step-by-step explanation:
This paper is 15 feet across on any side. Who will deliver this monster?
Area = s^2 where s is the length of 1 side.
Area = 225 feet^2 (You sure this isn't inches).
s^2 = area
s^2 = 225 Take the square root of both sides of the equation.
sqrt(s^2) = sqrt(225)
s = 15

Answer: -5
Step-by-step explanation:
You should get negative 5 because first you multiply and add a sign.
So for this question, you needed to add a negative sign because there are 2 negative signs and 1 positive. ( -,-,+) so if you do -1 x5, sinse you used one negative sign for the -1 and a positive sign for 5, you are left with a negative sign. So that is why you need to add a negative sign before our answer 5. on this question.
The result is x^2 +x +4 -21/(x+3).
