Answer:
what is your question?
Step-by-step explanation:
The formula for the area of a square with sides of length x is A = x2 so
x2 = 400 is the equation
This equation has 2 solutions, namely x = ±√400 = +20 or -20
The negative solution does not make sense because a length cannot be less than 0.
The total length needed to go around the painting is the perimeter of the square, which is
P = 4*x = 4*20 = 80 inches
It can only become a whole number when its over .99 such as 1.00 is a whole number and 7.24 is also a hole get it
Answer:
f(-2)=-12
Step-by-step explanation:

and solvee
f(-2)=-2^2+3(-2)-2
should be -12
