Answer:

x = -1

Step-by-step explanation:

since the 23 is positive you have to subtract it on both sides . which would give you -4x =4

then divide -4 on each side and you should get x = -1

a positive divided by a negative is always negative.

Math geometry show work Thanks

Problem 1, part (a)

<h3>Answer: False</h3>

For instance, 200 feet in real life can be reduced to scale down to say 2 inches on paper. So we have a reduction going on, and not an enlargement.

====================================================

Problem 1, part (b)

<h3>Answer: true</h3>

This is because a scale drawing involves similar polygons. This is true whenever any dilation is applied.

====================================================

Problem 2

I'm not sure how your teacher wanted you to answer this question. S/he didn't give you any numbers for the side lengths of the polygon. The angle measures are missing as well.

Calculat the length of the circumference of a circle with diameter of 8cm.

mr_godi [17]

Hello there!

The formula for finding the circumference of a circle is 2 $\pi$ r (or 2*3*r in your terms). Although we don't have the radius yet, we can certainly find it pretty easily. Keep in mind that the radius will always be half the diameter. So, let's find the radius.

8 / 2 = 4; now we have everything we need to solve for the circumference.

2*3*4 is our expression. Now let's simplify it.
2 * 3 = 6
6 * 4 = 24

Your circumference is 24cm.

I hope this helps!
