Algebra 1 which expressions are polynomials? a. z+1 b. 6+w c. 2x^4-y d. y^2−3√y+4 (the 3 is above? ? i cant format it)

Example C: w cubed z, +, 5, z squared, minus z squared, +, 6 For example, 2x + 1 = 7x and 10x minus 9y minus z = 3 are linear equations, but x, +, y ...

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
