How do you write and solve an inequality represents the values of x for which the area of the rectangle will be at least 35 square feet?

#x >= 35/w# where #w > 0# is the width of the rectangle (assuming #x# is the length)

Explanation:

There really is not enough information here. You have not indicated how #x# is related to the rectangle.

Perhaps (as an alternative to the assumption I made [above]), you meant for #x > 0# to be the length of one side of a square.
In this case:
#color(white)("XXX")x^2 >= 35#
#color(white)("XXX")rarr x >=sqrt(35)#
