Question

Which choice is the solution set for the inequality below , sqrt of x > 11 , I had put x>121 n got it wrong not sure what I need to do

Answer 1

Answer: Option B, x ≥ 121

Explanation:

We start with the inequality:

√x ≥ 11.

First, we can square each side of the inequality, to get:

(√x)^2 ≥ 11^2

And we know that:

√(x^2) = (√x)^2 = x

Then:

x ≥ 11^2

x ≥ 121

So we only need to have x equal or larger than 121.

The correct option is B.
