Find the 5th term in the expansion of (x – 3y)8

Lynna [10]

Not sure what you mean by 5th term, I assume it's the term with the form x^3y^5

Then, you can use combination method:

C(8,3) * (-3)^5 = -13608

So, 5th term is -13608x^3y^5

Helps me! find the area please. ＼（〇_ｏ）／

Anon25 [30]

We must remember the equation to find the area of a trapezoid first.
Area = $\frac{A+B}{2} *H$
A and B are the bases (6 and 12)
The height is 6 for each trapezoid
Now Solve!
====================================================================
SOLVING...

Area = $\frac{6 + 12}{2} * 6$
Area = $\frac{18}{2} * 6$
Area = 9 * 6
Area = 54

Since there are two trapezoids, multiply 54 by 2
54 x 2 = 108
Area = 108

What Properties or characteristics or similar triangles could be used to prove the Pythagorean theorem?

Zolol [24]

Well, in order to prove the Pythagorean theorem, every triangle you are using has to have one right angle (90-degree angle), and the side opposite to it will be called the hypothenuse. The remaining two triangles will be acute angles (<90 degrees), and the sides opposite to them are called sides/catheti.
