Answer:

x=0,x=-5

Step-by-step explanation:

Solve with the quadratic formula:

where

a=3,b=15,c=0

x=-15 + (sqrt 15^2-4*3*0)/2*3 :0

x=-15 - (sqrt 15^2-4*3*0)/2*3    :5

so the answer is x=0, x=-5

You are putting a rectangular hot tub on your back porch. It is 6 feet long, 5 feet wide, and 3 feet deep. How much will it cost
sleet_krkn [62]

It costs $ 3.4 to fill the hot tub

<h3><u>Solution:</u></h3>

Given that, You are putting a rectangular hot tub on your back porch

The rectangular hot tub is of shape cuboid

<em><u>The volume of cuboid is given as:</u></em>

\text{Volume of cuboid } = length \times width \times height

It is 6 feet long, 5 feet wide, and 3 feet deep

Therefore,

length = 6 feet

width = 5 feet

height = 3 feet

<em><u>Thus volume of rectangular hot tub is:</u></em>

volume = 6 \times 5 \times 3 = 90

Thus volume of rectangular tub is 90 ft^3

Convert feet to gallons

We know that,

1 cubic feet = 7.48052 gallon

Therefore,

90 cubic feet = 7.48052 x 90 = 673.247

Thus gallons of water tub can hold is 673.247 gallons

Given that it costs $ 5 per 1000 gallons

1000 gallons = $ 5

Therefore,

1 gallons = $ \frac{5}{1000}

<em><u>Find for 673.247 gallons</u></em>

673.247 gallons = \frac{5}{1000} \times 673.247 = 3.366235 \approx 3.4

Thus it costs $ 3.4 to fill the hot tub
