What is a compound inequality that represents all real numbers that are greater than -8 but less than 8

The inequality is "-8 < x < 8" that can also be expressed as x > - 8 and x < 8

Step-by-step explanation:

In this case there are two inequalities. The first one is for all real numbers that are greater than -8. In this case we will represent the real numbers as "x" and this inequality can be represented as:

x > - 8

The second inequality is for all real numbers that are less than 8, this can be represented as:

x < 8

To create the compound inequality we have two use both of the inqualities above:

-8 < x < 8

x > - 8 and x < 8

In this case we use and because the real number must satisfy both inequalities at the same time.

the answer is c. 23/3

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
