Multiply 8 and 6 by 3.5 and then times them together.
8x3.5=28
6x3.5=21
28x21=588
-9x(5-2x)Mutltiply the number outside of the parenthesis with the numbers inside the parenthesis
Final Answer: -45x+18x^2
This answer can no longer be simplified.
3(x-9)=-3
3x-27=-3
3x=24
X=8
Check: 3(8-9)=-3
So your number is 8
2-3n=n+10
so two less than three is subtracting two minus three. than three times a number; we dont know that number so we put it as a variable. in this case n. so they are multiplying right now. "is" means equals. than the same number, which is n, plus 10. so add ten with n.
For indicies, the numerator is the normal power, and the denominator is a root as such. So 1/2 would be square root, 1/3 would be cube root, 1/4 would be 4th root and so on.
So, 64^(1/3) is the third root of 64, which is equal to 4.
