Answer:
x = 144
Step-by-step explanation:
Sum of all angles of n-sided polygon = 180 * (n - 2)
Sum of all angles of 8-sided polygon = 180 * 6 = 1080
x + 129 + 132 + 136 + 124 + 141 + 158 + 116 = 1080
x + 936 = 1080
x = 1080 - 936
x = 144
24= 3*2^3
88= 11*2^3
664= 83*2^3 -> 83=11+72 = 11 + 2^3*3^2
664=2^3 (11+2^3*3^2) = 88 +(2^3*2^3*3^2) = 88 +(24^2)
8408= 1051 * 2^3 -> 1051= 83+968 -> 968 = 2^3 * 11^2
8408= 2^3 (83+2^3*11^2) = 664 +(2^3*2^3*11^2) = 664 +(88^2)
So:
a(n) = a(n-1) + a(n-2)^2
Lets check: 88+24^2= 664
664+88^2= 8408
Answer:

Step-by-step explanation:
For this, you check to see if any of these variables are the same. There are two x's, and 2 y's. So, you have to multiply x and x, which gives you 2x, and since you multiply the y's it will give you y^2.
So the answer will be
