Answer:
20(3m-2)
Step-by-step explanation:
In order to factor, you have to look for the greatest common factor, or what the biggest number could the two numbers be divided by.
In this case, both numbers can be divided by 20, and so we put the 20 outside of the parentheses.
This leaves with 3m and -2, which are left inside the parentheses.
Hope this helps :)
Answer:
15.22
Step-by-step explanation:
The equation of the circumference of a circle is 2(pi)r
This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)
so a simple formula is:
arc length in radians X radius
radius = 4 cm
the area that the question wants is the oposite
of the 142 degree section so 360 - 142 = 218
218 degrees * (pi/180) = 3.80482 rad
3.80482 * 4 = 15.21928 cm
