Step-by-step explanation:
The formula for percent change is
change/original.
So let's subtract 17 from 55 to find the change. 55-17=38
This is the change. Now we divide it by the original, 17.
38/17=2.235294
We're not done yet! We have to move the decimal point over to the right 2 spaces to make it a percentage. So, the percentage increase is
about 223.53 percent
I also think that the answer is B too
That is simple all you have to do is multiply the number of white cars by 9 and you will get your answer. 40*9=360
(4x – 7)(16x^2 + 28x + 49) is equivalen to 64x3 - 343!
2.586 is the answer cause you said mathematically
