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

Answer:

The approximate positive value of x is 0.92.

Step-by-step explanation:

Given,

$(x+5)^2 = 35$

$x+5 = \pm \sqrt{35}$

$x = \pm \sqrt{35}-5$

Thus,

$x = \sqrt{35}-5$ or $x=-\sqrt{35}-5$

By taking positive value,

$x = \sqrt{35}-5$

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

⇒ First option is correct.
