<h2>FALSE</h2>

No matter where you move the vertices of the polygon or the polygon itself, the rotated image will have the same corresponding side lengths and angle measures as the original polygon. Moving the center of rotation or changing the measure of the angle of rotation does not change this either.

The formula to change F to C is F equal 9/5 C + 32. If the temperature is 21.5 C what is it in F?

Answer:

F=70.7

Step-by-step explanation:

This is a simple substitution problem.

The formula to change Fahrenheit to Celsius is $F=\frac{9}{5}\left(C\right)+32$ .
They give you C, so substitute it into the problem, which would give you $F=\frac{9}{5}\left(21.5\right)+32$ .
Simplify the right side of the equation by multiplying $\frac{9}{5}$ by 21.5.
Now, add 32 to 38.7, which should have been your answer to the previous step.
You should now have F= 70.7 as your answer.
