Answer:

$x=\pm \sqrt{21}/7$

Step-by-step explanation:

We can add 9 to both sides of the equation to get $21x^2=9$ .

We can divide both sides of the equation by 21 to get $x^2=9/21$ .

We take the square root of both sides of the equation to get $x=\pm \sqrt{9/21}$ .

However, that isn't in the form we need.

We know that $\sqrt{9/21}=\sqrt{9}/\sqrt{21}=3/\sqrt{21}=3\sqrt{21}/(\sqrt{21}*\sqrt{21})=3\sqrt{21}/21=\sqrt{21}/7$

so the answer is really $x=\pm \sqrt{21}/7$ and we're done!

Answer:

A 3

Step-by-step explanation:

Let n = the number

a number decreased by 12

n-12

This is equal to 3 times the opposite =

3 times the opposite

3*(-n)

-3n

Setting the two parts equal

n-12 = -3n

Subtract n from each side

n-n-12 = -3n-n

-12 = -4n

Divide by -4

-12/-4 = -4n/-4

3 =n
