Answer:

Step-by-step explanation:

The enclosing rectangle is 24 units long and 12 units high. Its area is ...

(24 units)(12 units) = 288 square units

The white circles obviously cover more than half the area, so the only viable answer choice is 62.

If you want to go to the trouble to actually figure it out, you can find the area of each circle using the area formula ...

A = πr² = (3.14)(6²) = 113.04

Then both circles have an area of 2×113.04 = 226.08, and the shaded area is the difference between that and the rectangle area:

shaded area = 288 -226.08 = 61.92 ≈ 62

Please help u have to factor

enot [183]

Both terms have a $-m^2n$ in common, so we can pull it out. The factored form will be $-m^2n$ times whatever is left after pulling it out.

In the first term, we will have just 8 left since everything else in the term is factored out.

The second term has a $7m^4n^3$ left. Notice that both of these terms no longer have a negative sign since the negative was factored out.

The answer is $(-m^2n)(8+7m^4n^3)$
