5n + 7 = 7(n+1) - 2n

First distribute 7 to all terms inside the parenthesis

7(n) = 7n
7(1) = 7

5n + 7 = 7n - 2n + 7

Simplify. Combine like terms

5n + 7 = 5n + 7

True.

If you want to continue:

Isolate the n, move all variables to one side, and constants to the other

5n (-5n) + 7 (-7) = 5n (-5n) + 7 (-7)

0 = 0

True

Find the length of the arc on a circle with the radius of 2.4 km and is intercepted by a central angle measuring 150°. Leave you
djverab [1.8K]

Formula to find the arc length is:

s=\frac{\theta}{360} 2\pi r

Where, s= arc length,

r = radius of the circle

\theta = central angle in degrees.

According to the given problem, \theta= 150 and r =2.4.

So, first step is to plug in these values in the above formula to get the arc length.

s=\frac{150}{360} *2\pi *2.4

=\frac{5}{12} *2\pi *2.4

=0.41667*2\pi *2.4

=2\pi

So, arc length is 2\pi.

V = 792 m3

I am kinda guessing on this since you didn't provide a unit or label what the height, width, and length are. Also you should specify what prism...
