Step-by-step explanation:
Answer:
4.502
Step-by-step explanation:
Area of a square is given by
A=L*L = Length squared
20.275=L squared
Applying the square root to both sides of the equation gives L= 4.50222...
L = 4.502 correct to 4 significant figures
Eliminate the y’s via elimination (subtract both of the equations):
x^2 - x = 6
x^2 - x - 6 = 0
Factor the quadratic:
(x - 3)(x + 2) = 0
Set each equation equal to 0 and solve.
x - 3 = 0 , x + 2 = 0
x = 3 , x = -2
Plug in the 1st value for x into the second equation:
3 - y = -3
-y = -6
y = 6
Plug in the second value for x into the second equation:
-2 - y = -3
-y = -1
y = 1
