Pentagon - 5 sides = 5 x 4 = 20
Hexagon - 6 sides = 6 x 5 = 30
Nanogon - 9 sides = 9
20 + 30 + 9 = 59 IN TOTAL
R - 5 1/6 = 10
r - 31/6 = 10
+ 31/6 +31/6
r = 91/6
So, r = 91/6.
And, I am not sure if the second one I am doing in right or wrong, but I am just guessing.
I think you use substitution method here.
8(x-2)+9 = 14
8x-16+9 = 14
8x-7 = 14
+7 +7
8x = 21
x = 21/8
So, the answer is 21/8
HOPE THID HELPS AND I REALLY HOPE THAT THE SECOND ANSWER IS RIGHT!!!!!!
