General equation of a circle is

(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the center and r = radius. so here we have a = -4 and b = -6 and r^2 = 3^2 = 9

Therefore the equation of the required circle is

(x + 4)^2 + (y + 6)^2 = 9

What is the value of -6+3-3(-18) ?<br> (Need ASAP with steps!)
oee [108]
-6+3-3(-18)

Okay.

Work from left to right.
-6 plus 3 equals -3.
(Think of it as in a number line, from the spot of -6, move right three units. This will give you -3. Anyways..)

Now you have -3-3
The result is -6.

-6(-18)
Negative six times negative eighteen equals positive 108.

The answer is 108.

What is the volume of a rectangular prism with a length of 7m, a hight of 9m and a width of 11m
vazorg [7]
Hello!

To find the Volume of the Rectangular Prism, you'll need to multiply all of the measurements together. So you'll need to multiply 7, 9, and 11 together.

V=7*9*11

First, you'll need to multiply 7 and 9. Once you've multiplied 9 and 7 together, you should have 63. Now you should multiply 63 and 11 together. Once you've multiplied 63 and 11 together, you should have a Volume of 693

You should have a Volume of 693m³

I hope this helps!
