Answer:
SA = 202
Step-by-step explanation:
Surface area = Sum of all 6 areas of each side of the cuboid
SA = 2 (4·5 + 5·9 +9·4), because there are 2 of each kind of sides
SA = 2 (20+ 45 + 36)
SA = 2·101
SA = 202
Answer:
The center is (-3,2) and the radius is r=2
Step-by-step explanation:
The general equation of the given circle is

Add the square of half the coefficient of the linear terms to both sides of the equation to obtain;



The quadratic trinomials in x and y on the left side of the equations are perfect squares.
We factor to obtain;


Comparing to:

The center is (-3,2) and the radius is r=2
C= 20-0.75x
c= 20-0.75(9)
c= 20-6.75
c= 13.25
Here c is the amount of change and x is the number of books bought.
The customer's change will be $13.25
