Looking at the provided diagram â 7 and â 9 are alternate interior angles. The reason for this is that those two angles are on alternate sides of the transversal line c. And they're interior angles because they're on the inside of the two lines a and b that are being transversed. And because those two angles are equal to each other, that means that lines a and b are parallel to each other. With this in mind, let's look at the available options. A. aâ•‘b, Converse of the Alternate Exterior Angles Theorem * Yes, a and b are parallel. But â 7 and â 9 are alternate interior angles, not alternate exterior angles. So this is a bad choice. B. câ•‘d, Converse of the Same-Side Interior Angles Theorem * We don't have any basis to see if c and d are parallel to each other or not. So this too is a bad choice. C. aâ•‘b, Converse of the Alternate Interior Angles Theorem * a and b are parallel to each other, so the first part is good. And â 7 and â 9 are alternate interior angles, so the second part matches as well. This is the correct choice. D. not enough information to make a conclusion * This is just abandoning the problem and since we've already picked C, it's a bad choice.

What is the degree of the polynomial?

Maslowich

The Degree (for a polynomial with one variable, like x) is the largest exponent of that variable.

Let's check each terms :

 $3xy^2z$ has degree of 4 (x is an exponent of 1, y has 2, z is an exponent of 1. So 1+2+1 = 4).

 $2z^5$ has a degree of 5 (z has an exponent of 5).

$\frac{2}{3} y^2z^4$ has degree 6 ( y has 2 and z has 4. So 2+4=6).

Now that we have checked each terms, we know that the largest degree is 6, so the polynomial has a degree of 6.

In short, your answer be 6.

Please help me !!! and explain your answer !!! solve for L :

faltersainse [42]

L = $\frac{P}{2}$ - W

P = 2L + 2W = 2(L + W) → ( take out common factor of 2)

divide both sides by 2

$\frac{P}{2}$ = L + W

subtract W from both sides

$\frac{P}{2}$ - W = L

1a. 64*10^6 +5.4*10^6 = 69.4*10^6 = 6.94*10^7 . . . . square miles

1b. 6.4*10^7 +0.54*10^7 = 6.94*10^7 . . . . square miles
.. yes, we can find the same answer this way

2. The ratio of areas is 6.4*10^7/(5.4*10^6) ≈ 11.85
The Pacific Ocean is about 12 times the size of the Arctic Ocean.

The difference of areas is 6.4*10^7 -0.54*10^7 = 5.86*10^7
The Pacific Ocean is 5.86*10^7 square miles larger than the Arctic Ocean.
