Option C: 16 is the number added to both sides of the equation to complete the square

Explanation:

The equation is

We need to determine the number that is added to both sides of the equation to complete the square.

We need to write the equation in the form of

Solve for a:

Dividing by 2x, we have,

Thus, the value of a is 4.

To write the equation in the form of :

Adding to both sides of the equation, we have,

Complete the square,we get,

Hence, the number 16 is added to both sides of the equation to complete the square.

Thus, Option C is the correct answer.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
