Answer:
3a -2c +8
You have to combine the same letters together, which is only 2c and -4c. Then you just write the rest of the equation.
Answer:
270 in
Step-by-step explanation:
the least amount of fabric she would need is equal to the area of the mat

Answer:

Step-by-step explanation:
<u>Subtractive Areas
</u>
When we want to find areas of surfaces that are inside of greater surfaces, we must subtract the greater minus the rest of it. We want to find the shaded area which is part of the circular sector, along with a right triangle shown in the figure. The area of a circle is

The area of a circular sector of center angle \theta is

The area of a right triangle with base b and height h is

We have the value of
is


The radius is half the diameter, thus

The area of the circular sector is computed now:


We also have the length of the base as double of the given value (because of symmetry)


The height is

The area of the triangular surface is


Finally, the shaded area that Geneva will lose from the table is
