In the equation sqrt n+5 - sqrt n-10, what is the value of n?

1 answer:

6 0

First, square the entire problem. Then add the n's and subtract 10 from 5. You will then get 2n-5=0. Add 5 to both sides, then divide by two to get the answer. (2n=5, n=2.5)

Answer:

The answer to your question is the last option (x + 6)² = 13

Step-by-step explanation:

Data

x² + 12x + 23 = 0

Process

1.- Subtract 23 in both sides

x² + 12x + 23 - 23 = -23

2.- Simplify

x² + 12x + ( ) = - 23

3.- Complete the perfect square trinomial

x² + 12x + (6)² = -23 + (6)²

4.- Factor

(x + 6)² = -23 + (6)²

5.- Simplify

(x + 6)² = -23 + 36

6.- Result

(x + 6)² = 13
