412:515

Step-by-step explanation:

Given data

Carlos bought 515 Euros

He spent £412

We want to find the ratio of the purchase to the amount spent

In the form 1:n

We have our ratio of pound to euros has

412:515

the answer is d

step-by-step explanation:

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
