we know that
The sum of exterior angles of any polygon is
degrees
so

therefore
<u>the answer is</u>
the value of x is 
Circumference of Circle A is is 42pi.
It is the same for all circles. To find the circumference, one must use the constant equation of 2pir. This equation stays the same, no matter what.
Now.. notice the picture below
it has a front-and-back of 11x4
it has a left-and-right of 6x4
and a top-and-bottom of 6x11
now, if the Surface Area is less than 290in², then is cheaper to manufacture, because it uses less material to make the box
Answer:b= -0.5
Step-by-step explanation:
>-3b+2.5=4
>-3b=1.5(subtract 2.5 from both sides)
>b=-0.5 (divide both sides by -3)
Answer:
(x + 8) / 4 = (x - 3) / 2 | *4
x + 8 = 2 * (x - 3)
x + 8 = 2 * x - 6
8 = x - 6
14 = x
The number is 14.
(14 + 8) / 4 = (14 - 3) / 2
22 / 4 = 11 / 2
5.5 = 5.5
