Answer:
x=7
Step-by-step explanation:
To solve for x, we need to isolate it by itself. We can do that by getting rid of the 7. Since the 7 is being multiplied with the x, we need to divide by 7 to cancel it out. When doing something to one side of the equation, we must always to the same to the other.
Divide both sides by 7
x=7
294 can be broken down into 7^2 * 6
so √294 it can be written as 7<span>√6
24 can be broken down to 2^2 * 6
so </span>√24 can be written as 2√6
and 54 can be broken down to 3^3 * 6
so √54 can be written as 3√6
then you just add all these together: 7√6 + 2√6 + 3√6 = 12√6
so your answer is D
X=13, Subtract 9, And add 6 and 19 To both sides. then Divide by three
