Question

Evaluate 3+ the square root of x+7-the square root of 3x when x =9

Answer 1

~Hello There!~

This is the equation:

$3+\sqrt{x+7} -\sqrt{3x}$

Simply substitute 9 into wherever you see 'x'

$3+\sqrt{(9)+7} -\sqrt{3(9)}$

The answer you get is:

$7-3\sqrt{3}$

Hope This Helps You!

Good Luck :)
