If she gains a card that would be a positive 1, if she sells one that would be negative 1, and if she keeps one than that would be 0.
Answer:

Step-by-step explanation:
Given


Required
The equation of the function
The given parameters means that:


Calculate the slope (m)



The equation is then calculated using:

This gives:


Open bracket

Take LCM


Answer:

Step-by-step explanation:
The side length of a square is represented by the expression 2x + 5.
The area of a square is given as:

where a = length of side of the square
The area of the square is therefore:

The perimeter of a square is given as:

The perimeter of the square is therefore:

The difference between the area of the square and the perimeter of the square is:

The expression that represents the difference between the area and the perimeter of the square is:

Answer:
17×10^8 is greater
Step-by-step explanation:
The expontent comes first which gives you
1000000000 then you multiply that with 17 to get
1700000000
The formula for the volume of a cylinder is V=3.14r^2(h).
So substituting the volume: 20,403.72=3.14r^2(h).
To solve for ‘r’, divide both sides by 3.14h
r^2=6,498/h
Then find square root of both sides
r= sqrt(6,498/h)
Since ‘h’ is not specified here, it cannot be solved further.
