Step-by-step explanation:
Answer:
11/8x+1/6
Step-by-step explanation:
Get all into lcd: 12/24x - 16/24 + 21/24x + 20/24
33/24x+1/6 = 11/8x+1/6
N° 10
n - 5
n° 14
a) x + 1
b) x - 1
C= 2*pi*r
pi= approx. 3.14
So
The first one with the radius being 18 would be approximately 113.04
BECAUSE 18 * 2 = 36
36*3.14= 113.04
DO THE SAME PROCESS with the other values you were given...
Also if they give you the diameter the formula is C= d*pi
that formula is the same as c=2*pi*r ..... Use either... just remember when they give you the radius.... the radius is half of the diameter... so take the radius times 2 and times that by pi
When it asked for an approximation use 3.14 for pi.
I'm sure you can do the rest by yourself. I hope this helped!
