Which value of x makes the open sentence true? 10 +m2x< 15x-20? 0, 1, 2,3

x=3 if the m was a typo, idk what that means

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
