Answer:
6i
Step-by-step explanation:
First, I think you mean square root 18 and square root 2. (Let me know if thats right.)
Thus we have square root -36, which is simplified to 6i (we have to use imaginary numbers)
Y = 0 so
x^2 + 6x - 40 = 0
(x +10)(x - 4) = 0
x+10 = 0; x = -10
x - 4 = 0; x = 4
answer is C. x = -10 and x = 4

Answer:
12 cups of sugar
Step-by-step explanation:
The recipe uses 3 cups of sugar for every 8 cups of flour.
The diagram that models the ratio is the upper one with 3 pink squares of sugar and 8 green squares of flour.
If she uses 32 cups of flour, she is making 4 times the recipe since 32 = 4 × 8.
Then she also needs 4 times the amount of sugar.
4 × 3 = 12
Answer: 12 cups of sugar
