Tax is:
$52* (2.9/100)= $1.51
$52+ $1.51= $53.51
The total cost (including tax) is $53.51~
The complete equation is x^2 - 4x + (-2) = (-2)^2
<h3>How to complete the equation?</h3>
The equation is given as:
x^2 - 4x + __ = (__)^2
_____________________________
Take the coefficient of x
k = -4
Divide by 2
k/2 = -4/2
k/2 = -2
Square both sides
(k/2)^2 = (-2)^2
_____________________________
Add the result of the above computation to both sides of x^2 - 4x + __ = (__)^2
So, we have:
x^2 - 4x + (-2) = (-2)^2
Hence, the complete equation is x^2 - 4x + (-2) = (-2)^2

The answer is : $36.36
Step-by-step explanation:
The given box is a rectangular box. To find the felt needed to cover the box, we need to find the surface area of the rectangular prism.
Surface area of a rectangular prism = 2(l*w + w*h + h*l), where "l" is the length, "w" is the width and "h" is the height of the rectangular prism.
Given: l = 11 inches; w = 8 inches; and h = 6 inches.
Now plug in these given values in the above formula, we get
Surface area of the rectangular prism = 2 (11* 8 + 8*6 + 6*11)
= 2(88 + 48 + 66)
= 2(202)
= 404
The surface area of the rectangular prism = 404 square inches.
The felt cost 9 cents square inches.
Convert 9 cents to dollar.
9 cents = $0.09
To find the cost of the felt needed to cover prism multiply 404 by 0.09
The total cost = 404*0.09 = $36.36
