The equation to find x
First, calculate the area of the big rectangle using:

So:

The smaller rectangle

The difference between this areas give the area of the shaded region.
So:


Open brackets

<em>The above equation can be used to solve for x</em>
Answer:
7,854,000
because the 308 people would have to be at least 500 to round up to 7,855,000
Answer:
3
Step-by-step explanation
cause there are three rooms that need to be painted
A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)
-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared
so when you plug the numbers in the formula it is
A = 3.14 x 6^2(squared)
A = 3.14 x 36
A = 113.1
