Question 137100: what is the value of x when
xcube + 3x = 47
The question says that it has a solution between 3 and 4. what does this mean.
what should i take the value of a?
i have got the answer 5.52 and -8.52. is it right
What would happen if the question was like below
4xcube + 3x=20
what should i take the value of a is it 4?? and what should i do with the cube? does it affects the formula Answer by vleith(2983) (Show Source):
You can put this solution on YOUR website! cube means raised to the power of 3. So yes, cube really affects the problem.
Let's look at the first one.
Given: show the value is between 3 and 4.
Substitute in x = 3 = = which is less than 47
Now use 4 = = which greater than 47. So x lies beween 3 and 4.
Make sense?
