Answer: 13

Step-by-step explanation: In this problem we're asked to rewrite as addition and then evaluate.

It's important to understand that minus a negative means the same thing as plus a positive so we can change 5 - (-8) to 5 + (+8).

Now we can simply add to get a sum of 13.

Therefore, 5 - (-8) or 5 + (+8) = 13

Answer: 13

Step-by-step explanation: We originally have the equation 5-(-8).

Flip everything around.

5 + (+8)

5 + (+8) = 13.

When it gives the keywords "rewrite as addition" you should know that you need the rewrite the equation an opposite way of what it was written.

In this case it was 5-(-8).

Flip the signs, 5+(+8).

Add 5 to 8 and get 13.

Describe at least two differences between constructing an inscribed regular hexagon and constructing an inscribed square.
liberstina [14]

Correct answer is A.

The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction.

<h3>How to calculate the diameter?</h3>

If you know the radius of the circle, multiply by 2 to get the diameter. The radius is the distance from the center of the circle to the edge. For example, if the radius of a circle is 4 cm, then the diameter is 4 cm x 2 = 8 cm. If you know the circumference of the circle, divide by π to get the diameter.

<h3>Briefing:</h3>

The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction which is A.

The diameter of the circle is used for the square as l=2r therefore corresponds to the diameter, while for a hexagon r=r being the radius of the circle.
