Answer:
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
Answer:
n=−0.545455
Step-by-step explanation:
n(6.5)=−3+n
Simplify both sides of the equation.
n(6.5)=−3+n
6.5n=−3+n
6.5n=n−3
Subtract n from both sides.
6.5n−n=n−3−n
5.5n=−3
Divide both sides by 5.5.
5.5n
5.5
=
−3
5.5
