Answer:
Step-by-step explanation:
x^2-6=0
x^+6=0 ( add six to both sides)
x^2=6
x= the square root of 6 ( to get rid of the exponent you have to do the opposite....which is the square root)
x=2.44948974278
You may have to round if not given the exact number.
Option D is the correct one.
To equal the step 2, we would have to determine that 20 was our new denominator and multiply the first fraction by 5, the second by 4 and the 2 by 20.
multiplied by sides of the equation by 20
Expression: 5+5
Equation: 5a + 2b =5
Inequality: 2x > 2+5
