Answer:
B. (x-2)^2=12
Step-by-step explanation:
The constant that completes the square is the square of half the coefficient of the x-term. That value is (-4/2)^2 = 4.
There is already a constant of 2 on the left side of the equal sign, so we need to add 2 to both sides to bring that constant value up to 4.
x^2 -4x +2 = 10 . . . . . . . given
x^2 -4x +2 +2 = 10 +2 . . . . complete the square (add 2 to both sides)
(x -2)^2 = 12 . . . . . . . . . write as a square

Quadrilaterals</h3>
There are different types of quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, the opposite sides for a rhombus are equal and parallel.
The area for a rhombus can be calculated from:
- Base and Height - A = b * h
- Diagonals - A = 1/2 * D1 * D2
where:
b= base
h=height
d= diagonal
The question gives the total area (440m²) and the value of base (22 m). Thus,
A = b * h
440=22*h
h=440/22
h=20 m
