What is the simplified form of the following expression? 6c^2 + 2.5d - d + 2c^2 - 3d
motikmotik

<u><em>Answer:</em></u>

<u>The simplest form would be:</u>

8c² - 1.5d


<u><em>Explanation:</em></u>

To simplify an expression, we need to <u>gather the like terms</u>.

Like terms are the ones having the same variable raised to the same power


<u>In the given expression:</u>

6c² + 2.5d - d + 2c² - 3d


We have terms having c² and terms having d.

<u>Therefore, we would gather them as follows:</u>

6c² + 2.5d - d + 2c² - 3d

(6+2)c² + (2.5-1-3)d

8c² - 1.5d ......................> This is the simplest form


Hope this helps :)

Find the perimeter of the figure to the nearest hundredth.
Kryger [21]

Hello!

Your answer should be 26.85.

We can use the formula of pi d or 2 pi r for the circumference.

You would get 5 pi.

But since its not a full circle you would divide it in half and get 2.5 pi.

2.5 pi is equal to 7.85.

Now we can use the equation 7.85 + 7 + 7 + 5

That would equal our answer... 26.85!

Hope this helps!
