Answer:
Part 1) The area of the 4 walls is
Part 2) You will have to buy 2 gallons
Part 3) You will have to buy 3 gallons
Part 4)
Part 5) The area of the floor is
Part 6)
Part 7)
Part 8)
Step-by-step explanation:
Part 1) What is the area of all 4 walls together?
we know that
The area of all 4 walls together is equal to the perimeter of the floor multiplied by the height of the wall (8 ft)
so
The perimeter of the floor is
The area of the walls is
Part 2) If a gallon of paint covers 350 sq. ft., How many gallons will you have to buy?
using proportion
Remember that you can't buy a fraction of gallon
so
You will have to buy 2 gallons
Part 3) How many gallons will it take to put on 2 coats of paint?
Now the area will be
using proportion
Remember that you can't buy a fraction of gallon
so
You will have to buy 3 gallons
Part 4) If the paint costs $25 per gallon, and you are applying 2 coats of paint, how much will you spend on paint?
To find the cost multiply the number of gallons by $25 per gallon
so
Part 5) What is the area of the floor?
The area of the floor (rectangle ) is equal to multiply the length of the floor by the width of the floor
Part 6) What is the cost to redo the floor in oak?
To find the cost multiply the area of the floor by $6.75 per square foot

so
Part 8) What is the cost to redo the floor in carpet?
To find the cost multiply the area of the floor by $3.75 per square foot
so
Answer:
Option C
Step-by-step explanation:
Consider the function f ( x ) = 3x^2 + 4;
Now if this graph were to be translated 7 units down, considering the function was f ( x ) = 3x^2, the new graph would be f ( x ) = 3x^2 - 7. The same concept is applied to the graph f ( x ) = 3x^2 + 4;
* Note that a translation doesn't effect the rate with which the graph changes, it only effect's it's position on the coordinate plane
