12. find the area lying above the x - axis and below the parabolic curve y = 4x - x2.

a.8

b.8 1/3

c.10 2/3

d.16

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 !
