Gas cost $2.17 cents per gallon. he harvest for four days. he used about 38 gallons of gas in one day. what is the cost for the four days harvest

329.84

Step-by-step explanation:

(38 x 4) 2.17

Start by multiplying 38 times 4 (38 gallons of gas times four days)

38 x 4 = 152

He used 152 gallons of gas over 4 days.

Now, multiply 152 by 2.17 to find out how much it cost.

152 x 2.17 = 329.84

This man used $329.84 of gas in four days.

Best of luck.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
