Recall that +(-1) = -1.  Thus, +(-12) = -12.  Then you have -6n - 12 + 4n, or
                                                                                               12-4n (answer)
                                      This is equivalent to                          2(2n-6).  

You must also check 4(n-3) - 6n.  Is the end result the same as 2(2n-6)?

Kevin designs a sprinkler system for his yard. One rotation of the the sprinkler waters a circle with an area of 255pie square f
pantera1 [17]
The area of a circle can be found using:
pi x r^2 (where r is the radius)

If the area of the circle is 255pi, then:
pi x r^2 = 255pi

Now we need to make r the subject:

r^2 = 255 (cancel the pi on both sides)

r = square root of 255

r = 15.96871942

Answer: 15.96871942 feet
Hope the answer helps :)

Does anybody know how to do c on number five?
lbvjy [14]
Yes hi hello, it is not a linear function. It is a exponential function, because 64 divided by 2 equals 32, and 32 divided by 2 equals 16. The slope goes from -32 to -16. The equation is Y=64•(0.5 to the variable, X, power). (This is Lennox, Andrea’s friend who is smart.)
