Which expression is equivalent to n + 4 + n - 1 if no denominator equals zero?

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
