What is the solution of [tex]\sqrt{x-4}+5=2[/tex]?

A. [tex]x=-17[/tex]
B. [tex]x=13[/tex]
C. [tex]x=53[/tex]
D. No solution



Answer :

To solve the equation [tex]\(\sqrt{x - 4} + 5 = 2\)[/tex], we will follow these steps:

1. Isolate the square root:
[tex]\[\sqrt{x - 4} + 5 = 2\][/tex]

Subtract 5 from both sides:
[tex]\[\sqrt{x - 4} = 2 - 5\][/tex]

Simplify the right-hand side:
[tex]\[\sqrt{x - 4} = -3\][/tex]

2. Analyze the square root:

The left-hand side of the equation is a square root, [tex]\(\sqrt{x - 4}\)[/tex]. By definition, the square root of a number is always non-negative. This implies:
[tex]\[\sqrt{x - 4} \geq 0\][/tex]

However, we have [tex]\(\sqrt{x - 4} = -3\)[/tex], which is a contradiction since [tex]\(\sqrt{x - 4}\)[/tex] cannot be negative. Thus, this equation has no valid real solution.

3. Evaluate the given choices:

The given choices for [tex]\(x\)[/tex] are:
- [tex]\(x = -17\)[/tex]
- [tex]\(x = 13\)[/tex]
- [tex]\(x = 53\)[/tex]

None of these values will satisfy the equation [tex]\(\sqrt{x - 4} + 5 = 2\)[/tex] because the equation itself leads to an impossible scenario (square root equating to a negative number).

Therefore, the final conclusion is that there is [tex]\(\boxed{\text{no solution}}\)[/tex].

Answer:

D. No solution

Step-by-step explanation:

Given:

  • [tex]\sqrt{x-4}+ 5 = 2[/tex]

  1. Combine like terms

    [tex]\sqrt{x-4}= 2-5[/tex]
    [tex]\sqrt{x-4}= -3[/tex]

The square root of a number cannot be negative.

Therefore, the expression has No Solution
