Answer:

4x+14

Step-by-step explanation:

we know that in a rectangle, 2 sides are equal to one another (opposite sides), and the other 2 are equal to each other.

so,

2(5x+5) for the first 2 sides. you'd get 10x+10

2(2-3x) for the other two sides. you'd get -6x+4

add them up, and you'd get 4x+14

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?

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.
