The product is 
Explanation:
The given expression is 
We need to determine the product of the given expression.
First, we shall simplify the given expression.
Thus, we have,


Expanding the expression, we have,

Now, we shall apply FOIL, we get,

Simplifying the terms, we have,

Multiplying, we get,

Adding the like terms, we get,

Thus, the product of the given expression is 
Answer:
Option A.
Step-by-step explanation:
Circle contains all points in a plane that are equidistant from a point, i.e., center of the circle.
The locus of points 9 units from the point (-1,3) on the coordinate plane.
It means, the figure represents the set of all points which are 9 units from the point (-1,3).
So, the given describes a circle with of 9 units and center at (-1,3).
Therefore, the correct option is A.
The formula of a midpoint between X and Y:

We have the points X(7, 10) and Y(5, -8). Substitute:

<h3>Answer: (6, 1)</h3>
