Step-by-step explanation:

a) (s+r)(x) = s(x) +r(x) = (x+1) +3x²

  (s+r)(x) = 3x² +x +1

__

b) (s-r)(x) = s(x) -r(x) = (x +1) -(3x²)

  (s-r)(x) = -3x² +x +1

__

c) (s·r)(-3) = s(-3)·r(-3) = (-3+1)·(3(-3)²) = (-2)(27)

  (s·r)(-3) = -54

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 !
