Answer:
F and D
Step-by-step explanation:
When a negative number is multiplied by a positive number, the result is a negative number. When a negative number is multiplied by another negative number, the result is positive. 
 
        
                    
             
        
        
        
The rectangle with maximum area will actually be a square.
Each side will be of length  7/4 = 1 3/4.
        
             
        
        
        
to get an A, she needs >=160 points and she already has 125 points
let 'x' be the number of points on the last part of her project then
125 + x >= 160 
x >= 160 - 125 
x >= 35 
Sarah needs at least 35 points on the last part of her project.

Therefore, the equation of circle is: 
<h3><u>
What is a circle?</u></h3>
- All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant. 
- The radius of a circle is the separation between any point on the circle and its center. 
- The radius must typically be a positive integer. Except when otherwise specified, this article discusses circles in Euclidean geometry, namely the Euclidean plane. 
- A circle, specifically, is a straightforward closed curve that separates the plane into its inner and exterior.
Here we know that but we are not given the radius.
but we are not given the radius. 
However, we can find the radius by using the distance formula. 
 , where
, where  and
 and 
Putting the values, we get: 

The radius comes out to be: 

An equation of the circle with center  and radius r is
 and radius r is 

Now, substituting the values, we get:

Therefore, the equation of circle is:
