(2/3)*x - (1/2)*x = 3
*make common denominators
(2*2)/(2*3)*x - (3*1)/(3*2)*x = 3
(4/6)*x - (3/6)*x = 3
(1/6)*x = 3
x = 3*(6/1)
x = 3*6
x = 18 gallons of gas

The prime factor of 42 is : 1,2,3,6,7,14,21,42
Answer:
The third (C) option is the answer.
Because 4 is repeating in x coordinate,
that is called <u>D</u><u>o</u><u>m</u><u>a</u><u>i</u><u>n</u>.
It's allowed to be repeated in y coordinates,
that is called <u>R</u><u>a</u><u>n</u><u>g</u><u>e</u><u>.</u>
Good luck!

The solutions or roots to this equation is found by solving for x. We can do this a couple ways either by FOIL or quad formula
3x^2+6x+6=0
3(x^2+2x+2)=0
x^2+2x+2=0 we cant FOIL this out so we use the quad formula
x= [(-b+\-sqrt(b^2-4ac))/2a]
x= -2+\- sqrt(4-4(1)(2))/2(1)
x= -1 +i , -1 - i
So we have complex roots since our quad formula returned a negative number. Whenever the quad formula answer is positive we have two roots/solutions, when it is zero we have one root/solution, and whenever it is negative we have Complex roots/solutions
Hope this helps. Any questions please just ask. Thank you.
