Answer:
Step-by-step explanation:
2x^3(x^2 + 5x - 11)
Given:
The edge length of a cube is changing at a rate of 10 in/sec.
To find:
The rate by which cube's volume changing when the edge length is 3 inches.
Solution:
We have,
We know that, volume of cube is
Differentiate with respect to t.
Substituting 
and a=3, we get
Therefore, the volume increased by 270 cubic inches per sec.
Answer:
9+10 =21!
Step-by-step explanation:
Answer: there were 15 tiles in each box
Step-by-step explanation:
Let the number of tiles in each full box be x
Suppose, instead, that Bruce used 6 full boxes of tiles plus an additional 2 tiles. It means that he used a total of
(6x + 2) tiles
Suppose, that Felicia used 5 full boxes of tiles plus an additional 17 tiles. It means that he used a total of
(5x + 2) tiles.
If they each used the same number of tiles, it means that the total number of tiles used by Bruce = total number of tiles used by Felicia. Therefore,
6x + 2 = 5x + 17
6x - 5x = 17 - 2
x = 15
