Question

2. Which number makes the
inequality true?

x² + 3 <15

3 4 5

Answer 1

3

Explanation:

we solve this very similar to regular equations.

x² + 3 <= 15

x² <= 12

x <= sqrt(12) = 3.464101615...

the only number in the answer options that is smaller or equal to sqrt(12) is 3.

4 is already too large.
