What is the value of x in the equation 25x^2=16? A. + 5/4 B.+4 C. + 4/5 D.+16/25

x = ± 4/5

Step-by-step explanation:

25 x^2 = 16

Divide each side by 25

25 x^2 / 25 = 16 / 25

x^2 = 16 / 25

Take the square root of each side

sqrt (x^2) = ±sqrt (16/25)

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

x = ±sqrt (16) / sqrt (25)

x = ± 4/5
