4x^3-8x^2-9x+18
X(4x^2-8x-9)+18
There were 20 erasers added to each box, because 15 plus 20 is 35. 85 plus 20 is 105, and 35 times 3 is 105. This means that there are 35 erasers in box B after adding 20, and 105 erasers in box A after adding 20. I hope this helps you!
That's 20% of 305.
You could set up the problem as a ratio.
20 x
--- = ------
100 305
100x = 6100
x = 61
Answer:
no
Step-by-step explanation:
They are not the same because in the first example: (2,3) the 2 is on the x axis and 3 is on the y axis
In the second example: (3,2) the 3 is on the x axis and the 2 is on the y axis. Therefore the two points are not the same
So try and recognize the pattern. For level 1, you have 1 box and 12 cans. In 2, you have 3 boxes and 36 cans. 12/1 is 12, 36/3 is 12 and so on. The # of boxes times 12 is the number of cans. The # of boxes in the display is equal to the total number of boxes in each level. Level 5 will mean 1+2+3+4+5=15. Level 6 is 1+2+3+4+5+6=21. So if 6 has 21 display boxes, we can do 21*12 and you will get 252. Your answer is E, 252 cans.
