What is the sum of the square root of -2 and the square root of -18?

4 sqrt(2) i

Step-by-step explanation:

sqrt(-2) + sqrt(-18)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(-1) sqrt(2) + sqrt(-1) sqrt(9) sqrt(2)

The sqrt(-2) =i

sqrt(2) i + 3sqrt(2) i

4 sqrt(2) i

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

x=0
