Answer: 17.5 units.
Step-by-step explanation:
The triangle LAY is a similar triangle to LYW. It has the same angle measures, but different side lengths. The hypotenuse of LAY is the line LY, while the hypotenuse of LYW is the line LW.
We can use the line LY to find LW.
Use the Pythagorean Theorem to find LY:
(3.5)^2 + 7^2 = 61.25
So, LY has a length of
.
You can then use proportions to find the distance of LW.
The line LA is the base of the smaller triangle, and the line LY is the base of the larger triangle.
The line LY is the hypotenuse of the smaller triangle, and the line LW is the hypotenuse of the larger triangle.

You can then cross multiply to get this equation:

So, the line LW has a length of 17.5.
He would have to wash 20 cars at first i got 19.25 because i divided 231 by 12 but i rounded up to 20 just to be safe....
Answer:
285 mi
Step-by-step explanation:
We can see that for every gallon, Josh drives 30 more miles. This means that he will drive 30*9.5 mi.
30*9.5 = 285
Remember that multiples are numbers that can be divided by a number without a remainder so in this case you could add 15 by 15 to find what number in this set is a multiple of 15.




Therefore your answer is "60."
Hope this helps.
I think the answer is 22mn2+66m2n-64 since there are no more like terms
