If you want to inscribe a polygon inside a circle, you have a formula that doesn't have to use the apothem. The formula is:
A = (nr²/2)sin(360/n)
Since the polygon is a hexagon, it has 6 sides. Thus, n = 6. Knowing the area, we can determine the radius of the circle, r.
166.28 = (6r²/2)sin(360/6)
r = 8 inches
Thus, the radius of the circle is 8 inches.
Answer:
(2x-5)(3x-2)
Step-by-step explanation:
1)When factoring quadratic equations in for ax²+bx+c you need to separate the b term in a way that the two addends you separate it by should equal a•c. Just do trial and error. In this case you should get -4 and -15. Your separated equation should be:
6x²-4x-15x+10
2)now factor out a common factor from the first two terms and one from the last two terms you should have:
2x(3x-2)-5(3x-2)
3)finally rewrite this equation into two separate factors and you have your answer.
Part a y=95x
Part b 285=95•3
Part c ?
Hope I helped sorry I don't know how to do the last one!
A= 5 + 2 = 7
You get this by doing the inverse operation so minus 2 by 2 and 7 then you get your answer so it should look like this
X+2= 7
-2. -2
———
X= 5
B: 15-4=11
+4. +4
————-
X= 15
C: 4(3) = 12
D: 50/5 = 10
Btw this should be easy, try doing it on to your own now.
