Prove the following statement.
gayaneshka [121]

Answer:

You can prove this statement as follows:

Step-by-step explanation:

An odd integer is a number of the form 2k+1 where k\in \mathbb{Z}. Consider the following cases.

Case 1. If k is even we have: (2k+1)^{2}=(2(2s)+1)^{2}=(4s+1)^{2}=16s^2+8s+1=8(2s^2+s)+1.

If we denote by m=2s^2+2 we have that (2k+1)^{2}=8m+1.

Case 2. if k is odd we have: (2k+1)^{2}=(2(2s+1)+1)^{2}=(4s+3)^{2}=16s^2+24s+9=16s^{2}+24s+8+1=8(2s^{2}+3s+1)+1.

If we denote by m=2s^{2}+24s+1 we have that (2k+1)^{2}=8m+1

This result says that the remainder when we divide the square of any odd integer by 8 is 1.

The directions are with the pic below. I have to send a 2nd pic. Couldn’t fit everything on the page
Nonamiya [84]

If the pentagon is rotated 360° about the origin, that means the new figure will be exactly in the same position as the original image, because a rotation of 360° about the origin doesn't change the figure position or orientation.

So, if the vertex was located at (10, -8), the new figure will also have a vertex located at (10, -8).

Therefore the correct option is the fourth one.

The area of a rectangular wall of a barn is 133 square feet. It's length is 12 feet longer than the width. Find the length and w
GuDViN [60]
I'll give you a few hints. Area of a rectangle is length times width. We know that length times width is 135 sq ft, so we can express it as: 

<span>L * W = 135 </span>

<span>Now, L is 6 feet longer than width (L = 6 + W). Something tells me this is going to involve a quadratic formula then plugging in values into our original equation. </span>
