Answer:
The number you would add to both sides of the equation to use the "Completing the Square" method would be 16.
Step-by-step explanation:
To find the number to add to both sides of an equation to complete the square, divide the first-degree term's coefficient by 2 and square your remainder. In this case, the coefficient of the first-degree term is -8. After dividing by 2 and squaring it, you'll get 16, so that is the number you must add to both sides of the equation in order to complete the square.

Answer:
C. 43.6
Step-by-step explanation:
you need to take the area of each shape
lets do the skinny triangles first on the top and bottom of this shape.
so to find the formula of triangle we need to do 0.5 * 1.26 * 5.3
because the formula of a triangle is half the base times height.
so we get 0.5 * 1.26 * 5.3 = 3.339
multiply it by two and we get 6.678
now lets find the area of the huge rectangle on the back/behind of the shape
3.3*5.3 = 17.49
now lets find the area of the two smaller rectangles
3.3 * 3.6 = 11.88
2.3 * 3.3 = 7.59
now lets add
6.678 + 17.49 + 11.88 + 7.59 = 43.638
round it to 43.6
