Question

Find the exact value of x.
Thank you

Answer 1

Explanation:

Using the same proportion as the previous question

11/x = x / 8 Cross multiply

x^2 = 88 Factor 88 into at least 1 perfect square and something

x^2 = 4 * 22 Take the square root of both sides

x = sqrt(4 * 22)

x = 2*sqrt(22)
