Answer 1

need an answer for this question

Answer 2

You don't need an answer , you need to know how to do this type of question.

But first of all, fix your post, since
"..solve w fair is partly x and partly as the square of x.." makes no sense to me.

Answer 3

poor dictation
"w fair is " probably means "w varies"
so, now it appears that
w = ax + bx^2
and thus that
3a+9b = 18
5a+25b = 165
Now just solve for and a and b as usual
