Question

If (x + 5)^2 = 35, what is the approximate positive value of x?

0.92
2.65
3.16
5.48

Answer 1

the approximate value of x = 0.92

Answer 2

The approximate positive value of x is 0.92.

Explanation:

Given,

`(x+5)^2 = 35`

`x+5 = \pm √(35)`

`x = \pm √(35)-5`

Thus,

`x = √(35)-5` or
`x=-√(35)-5`

By taking positive value,

`x = √(35)-5`

`x=5.91607978 - 5 = 0.91607978\approx 0.92`

⇒ First option is correct.
