X^2 – 12x + 36 = 0
(x-6)(x-6)=0
x=6 x=6
Not a solution
x^2 + 12x – 36 = 0
Doesn't factor
Not a solution
x^2 + 36 = 0
x=√-36
Not a solution
x^2 – 36 = 0
(x-6)(x+6)= 0
x=6 x=-6
Solution
ANSWER: The equation with solutions of x=6 and x=-6 is the last choice: x^2 - 36= 0.
Hope this helps! :)
B use it to be a little easier and easier to get it out and then I will have it to do with the new update I need it bye to my friends love love you love bye love love miss bye love love you love bye love love miss bye love love you
This is how I'd set it up:
405/20 = 243/x
this means the mpg (miles / gallons) for 1 situation is the same as the mpg for the other situation (because the rate is the same)
then just cross multiply and solve:
405x=243*20 or 405x=4860 or x = 12
he would need 12 gallons of gas for 243 miles
Answer:
12 just because I need the free credit things sorry this ain't gonna be helpful lol
<em>Answer: A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system. Hope this helps.</em>
