You have a rectangular pool 15 X 30 X 5 feet

The floor of the pool is 15X30 = 450 ft2
Two sides are 5X15 = 2(75) = 150 ft2
Two sides are 5X30 = 2(150) = 300 ft2

Total area to be painted: 900 ft2

(900 ft2)/(250 ft2/gal) = 3.6 gallons
Since we can't purchase .6 gallons we
must purchase 4 gallons of paint

The volume of the pool is 15X30X5 = 2250 ft3
1 ft3 = 7.48 gallons
2250(7.48) = 16,830 gallons of water

Brilliant_brown [7]

Answer:

A

Step-by-step explanation:

the function f(x) is a straight line. The "-4" means that the graph moves down 4 units. Point A is at y=-4, so this is the point. You can graph the equation and you'll see that it hits point A.

Read the question on the picture.
Marizza181 [45]

These two lines are congruent (the same) so we can set them equal to each other and solve.

5x-4=3x+6

The first thing we need to do is subtract 3x from both sides leaving us with 2x-4=6

Now we can add 4 to both sides leaving us with 2x=2

Now we need to divide both sides by 2 to get x alone.

Giving us our final answer of x=1
