Answer:
96
Step-by-step explanation:
eighth multiple of 12 = 12 * 8 = 96
The first table because the y side is increasing at the same rate. the rate is 4
Use the binomial theorem:
![\displaystyle (2x-9)^5 = \sum_{k=0}^5 \binom5k (2x)^{5-k}(-9)^k = \sum_{k=0}^5 \frac{5!}{k!(5-k)!} 2^5 \left(-\frac92\right)^k x^{5-k}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%282x-9%29%5E5%20%3D%20%5Csum_%7Bk%3D0%7D%5E5%20%5Cbinom5k%20%282x%29%5E%7B5-k%7D%28-9%29%5Ek%20%3D%20%5Csum_%7Bk%3D0%7D%5E5%20%5Cfrac%7B5%21%7D%7Bk%21%285-k%29%21%7D%202%5E5%20%5Cleft%28-%5Cfrac92%5Cright%29%5Ek%20x%5E%7B5-k%7D)
The <em>x</em> ³ terms occurs for 5 - <em>k</em> = 3, or <em>k</em> = 2, and its coefficient would be
![\dfrac{5!}{2!(5-2)!} 2^5 \left(-\dfrac92\right)^2 = \boxed{6480}](https://tex.z-dn.net/?f=%5Cdfrac%7B5%21%7D%7B2%21%285-2%29%21%7D%202%5E5%20%5Cleft%28-%5Cdfrac92%5Cright%29%5E2%20%3D%20%5Cboxed%7B6480%7D)
Answer:
x = 35
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Then
1 exterior angle = 360° ÷ 8 = 45° , so
x + 10 = 45 ( subtract 10 from both sides )
x = 35
