Let x represents the numbers of hours that Billie and Toni are driving after first day and ‘Y’ represent the distance they have passed distance
Y=420+65
And, first day they traveled : 410 mi
2nd day they traveled =65.8=520 mi
3rd day they traveled =65.8=520
By the end of the third they traveled= 420+520=520
1460 mi
Answer is choice B
The ratio of the sides (first to the second) is 11/9 since we divide 22/18 and reduce that fraction
Once we know the scale factor is 11/9, we square it to get (11/9)^2 = 121/81 which is the ratio of the first area to the second area
Answer:
3x = 4-x "hope this helps"
Step-by-step explanation:

Generally what I like to do, to solve questions like this is to substitute the given answers into the equation to solve this faster...
Equation: x^2 + 10x + 12 = 36
A.) (-12)^2 + 10(-12) + 12 = 36
144 - 120 + 12 = 36
24 + 12 = 36
36 = 36
(2)^2 + 10(2) + 12 = 36
4 + 20 + 12 = 36
24 + 12 = 36
36 = 36
Since we found the answer with the first try, we already know the correct answer is A.
So...
The Correct answer is: A.) x=-12 or x=2
