10. Which one of the following is a polynomial? a) 2x^(1/2) -1
b) x-1/x+1
c) x²+ 3x^(3/2) / x^(1/2)
d) (x² / 2) - (2 / x² )
​

i dont know sorry

step-by-step explanation:

cause it equals more

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
