3(6a\times{b^2})\\=3(6ab^2)\\=18ab^2

Need help #14 <br> The center of the circle is (0,-8). The radius is 9.
Shtirlitz [24]
X^2+ (y+8)^2 = 81.....this is C.
X^2 + y^2 + 16y +64=81 so x^2 + y^2 + 16y = 17.....this is D.

So I’d say C and D are correct

Hey can someone help me with #17
Vinvika [58]
D. 54° as you know an external angle has to equal up to 360 

when you start plugging in 360 by 36 gives you 10
360 by 40 gives you 9
360 by 45 gives you 8
360 by 54 gives you 6.666 repeating you know that it isn't possible
you cannot have a repeating number of sides as an angle measure
that's how you get that answer
