Answer:
20.65 points.
Step-by-step explanation:
We have been given that a star athlete at a local college scored 640 points during the 31 basketball games. We are asked to find the average number of points she scored per game.
To find the average number of points scored per game by player we will divide total number scored by the total number of games.


Therefore, the average number of points scored per game by the player is 20.65 points.
The correct quadratic equation;
x2+7x-2=0
Working
Assuming the frame has a uniform thickness;
Then length of mirror and frame is 3+x and width 2+x
The area of mirror and frame area;
A=L*W
8=(3+x)(2+x)
8=(6+5x+x2)
Taking 8 to the Right hand side, we have:
x2+5x-2 =0
