Answer:

$\frac{3}{10}$

Step-by-step explanation:

5 = 5 × 1

2 = 2 × 1

LCM = 2 × 5

$\frac{2(4)}{2(5)} -\frac{5(1)}{5(2)}$

$\frac{8}{10} -\frac{5}{10}$

$\frac{3}{10}$

Which numbers are solutions to the equation 30=x2

GaryK [48]

Answer:

x = +√30

Step-by-step explanation:

Please write 30 = x squared as 30 = x^2.

If x^2 = 30, there are two solutions: x = +√30 and x = -√30.

Several possible answers are given. x=30−−√ is closest to the correct one, but must be written as x = √30. Please ask someone how to find the "√" operator in Brainly. Or, just write "sqrt( )" instead.
