Answer:
Option B is correct
Step-by-step explanation:
We need to solve the equation 3x^2 = 18 3/4 to find the value of x
3x^2 = 18 3/4
Converting mixed fraction into fraction form
3x^2 = 75/4
Dividing both sides by 3
3x^2/3 = 75/4*3
x^2 = 75/12 (dividing numerator and denominator by 3 which is common factor)
x^2 = 25/4
Taking square root on both sides to find value of x
√x^2 = √25/4
x = ± 5/2
x = ± 2 1/2
So, Option B is correct.
