none of these

d. 7/9

Step-by-step explanation:

The total points earned by both Joy and Denise: 5/9 + 2/9 = 7/9

7/9

Step-by-step explanation:U basically add 2/9 and 7/9 coz they have the same denominators

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
