Solve the following quadratic equation:
Advocard [28]

Answer:

-3.5 or -6

Step-by-step explanation:

2x^2+19x+40=-2

2x^2+19x+40+2=0

2x^2+19x+42=0

2x^2+(12+7)x+42=0

2x^2+12x+7x+42=0

2x(x+6)+7(x+6)=0

(x+6)(2x+7)=0

either,

x+6=0

x=-6

or,

2x+7=0

2x=-7

x=-7/2

x=-3.5

If 4 gal of premium unleaded gasoline costs $15.04, how much would it cost to completely fill a tank whose capacity is 9-gal?
Sveta_85 [38]

Answer:

$33.84 cents

Step-by-step explanation:

Given the following question:

4 gallons = 15.04
1 gallon = ?

How much for 9 gallons?

To find the answer we have to find how much one-gallon costs since we already know how much it costs for 4 gallons of this unleaded gasoline.

15.04\div4
15.04\div4=3.76
=3.76

One gallon of this gasoline costs $3.76 now we need to find how much it costs for 9 gallons.

3.76\times9=33.84
=33.84

For nine gallons of gasoline it will cost you "$33.84 cents."

Hope this helps.
