Does is have a total perimeter of the triangle? If not, the closest you can get is by simplifying.

What should be done to both sides of the equation in order to solve y - 4.5 = 12.2?

maw [93]

Y - 4.5 = 12.2

your solving for y which means your trying to get rid of 4.5 so that y can equal something. The opposite of -4.5 would be +4.5, so you would add 4.5 to both sides to get

y = 16.7

So your answer would be

A. Add 4.5

and also dont' say your stupid because all you need is a little explanation and you'll get it, its very easy you just need to take the time to practice :-)

The area of the shaded sector is one-fourth of the area of the whole circle so:
$area = r^2 \pi \\ area = 6^2 \pi \\ area = 36 \pi$
area of shaded region $= \frac{36 \pi }{4} \\ area = 9$
The area of the shaded region is 9pi units^2
