Describe the points with a double inequality. I need the answer quick. Thanks!

Step-by-step explanation:

We want to describe the solution set on the number line as an inequality.

We have open circles at both ends.

This means the inequalities are not the ones containing equal sign.

The number line started from -3 and ended at 13 non inclusive.

This means the solution set for the inequality are all real numbers greater than -3 but less than 13.

We write this as:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
