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 is 3.75%
3.75% = 0.0375
0.0375 + $2,100 = <span>$78.75</span>
Using squares of integers numbers, it is found that the solution of the equation is located between the integers x = 1 and x = 2.
The equation given is:

The solution of the equation given is:

The squares of the integers numbers until the square root of 3 are:


Since
, the square root of 3, which is the solution to the equation, is located between the integers x = 1 and x = 2.
