Answer: 2k

Step-by-step explanation:

Like terms are terms that have the same variables and powers.

k is the same variable so you would take away k (or 1k we just don’t write 1k in algebra) from 3k=2k

Write the equation in standard form for the circle with center (-7,0) and radius 3√3.
mario62 [17]

Answer: (x +7)^2 + y^2 = 27

Step-by-step explanation:

The standard form of a circle is written as such:

(x - h)^2 + (y - k)^2 = r^2

Where (h, k) is the center of the circle, and r is the radius.

We know that the center is (-7, 0), so we can plug that into the equation like this: (x +7)^2 + y^2 = r^2

The radius is 3 * the square root of 3. To square this, we can multiply 3 squared and the square root of 3 squared:

3^2 * \sqrt{3} ^2 = 9 * 3

So, your standard form equation is the following:

(x +7)^2 + y^2 = 27
