Well, you know just by looking at it because it ends in an even number. Like, the greatest common factor of 4 is 2, 1.) Because no other number can "go into it," and 2.) Because it's even.

Answer:

Check below

Step-by-step explanation:

That's too bad you haven't attached a rectangle.

Here's an example, with the data you've typed in.

1) When we dilate a rectangle we either grows it or shrink it through a scale factor.

Check the first picture below.

The New Dilated Rectangle A'B'C'D' will follow its coordinates, when the <u>Center of Dilation is at its origin(Middle):</u>

D_{A'B'C'D'}=\frac{1}{2}(x,y)

2) But In this question, <u>B is the center of Dilation</u>. So, Since B is the Dilation Point B=B' .  And More importantly:

\bar{AB}=\frac{1}{2}\bar{A'B'}\\\bar{CD}=\frac{1}{2}\bar{C'D'}\\\bar{AC}=\frac{1}{2}\bar{A'C'}\\\bar{CD}=\frac{1}{2}\bar{C'D'}\\

3) So check the pictures below for a better understanding.

Because of the rainy season, the depth in a pond increases 3% each week. Before the rainy season started, the pond was 10 feet d
Dafna11 [192]

It's not perfectly clear, but you seem to be saying that each week, the
pond becomes 3% deeper than it was THE PREVIOUS WEEK.

If I'm reading that correctly, then the pond is 10-ft deep when the rainy
season begins, and after 'x' weeks later, the depth is

                     D = 10 (1.03)^x            feet.

After 8 weeks, the depth is        D = 10 (1.03)⁸  =  12.67 feet .

                         rounded to the nearest foot,  D = 13 ft.
