Question 5 (2) x cube - 3x square 9x - 5

Mathematics

Please, post the instructions along with your question, and if possible share the question in symbolic form, not in words.

Do you mean Question #5?  By  (2) x cube, do you mean 2x^3?

I strongly suggest that you use lots of parentheses (   ) to show how your numbers are grouped, and not to use " x " to denote multiplication (use " * " for that, please.    

If only you'll clear this up, I'd be happy to help.

I will assume that your post is   2x^3 - 3(9x-5)^2.

Then 2x^3 - 3(81x - 90x + 25).  Does this have any resemblance to what you wanted me to see in your post?

Find the midpoint of the segment below
aniked [119]
1.
If we are given 2 points A(a, b) and B(c, d), 

the midpoint M, of segment AB has coordinates:

M_A_B=( \frac{a+c}{2} ,  \frac{b+d}{2} )

2.
We are given the points A(2, 3) and B(10, 3)

the midpoint of AB, is given by the above formula:

M_A_B=( \frac{2+10}{2} , \frac{3+3}{3} )=(6, 3)

3. 
Remark, since the segment is horizontal, that is the y-coordinate of both points is 3, the y coordinate of the midpoint will also be 3.

While the x coordinate is still found by \frac{2+10}{2}

Answer: (6, 3)
