Answer:180(D)
Step-by-step explanation: First, do 72/x=40/100. Then, cross muliply which is 7200 and 40*x. do 7200/40. The answer should be 180.
35 x 8 = 280
64 x 2 = 128
71 x 5 = 355
53 x 9 = 477
92 x 8 = 736
And that’s all I can clearly see
![\\ \sf\longmapsto y+124=180](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20y%2B124%3D180)
![\\ \sf\longmapsto y=180-124](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20y%3D180-124)
![\\ \sf\longmapsto y=56°](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20y%3D56%C2%B0)
now using angle sum property
![\\ \sf\longmapsto x+54+125+65=360](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20x%2B54%2B125%2B65%3D360)
![\\ \sf\longmapsto x+179+65=360](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20x%2B179%2B65%3D360)
![\\ \sf\longmapsto x+244=360](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20x%2B244%3D360)
![\\ \sf\longmapsto x=360-244](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20x%3D360-244)
![\\ \sf\longmapsto x=116°](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20x%3D116%C2%B0)
For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have
![5(3s^{11}-5s^4)](https://tex.z-dn.net/?f=5%283s%5E%7B11%7D-5s%5E4%29)
As for the literal part, you can factor
because it's the power of s with the smallest denominator. So, we have
![5s^4(3s^7-5)](https://tex.z-dn.net/?f=5s%5E4%283s%5E7-5%29)
Answer: 720
Step-by-step explanation: So this question really is just about subtraction and addition so as you can tell 630 is lower than 693 so if you add to where it is a 693 you need to add 63. But if you look at 720 its higher so you need to subtract and if you subtract to 693 then you need to subtract 27. So 27 is less than 63.
