According to the graph, what is the value of the constant in the equation
below?

answer:

step-by-step explanation:

hello :

hello :

25= a/4

20=a/5

10=a/10

5=a/20

a= 25×4

a= 20×5

a= =10×10

a= 5×20

so : a=100

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
