Hm thats a tough on ok add 7 and 2 and minus five
Alright, so the distance formula is sqrt((x1-x2)^2+(y1-y2)^2), and plugging that in, we get sqrt((0-3)^2+(3-10)^2)=sqrt((-3)^2+(-7)^2)=sqrt(9+49)=sqrt(58)=around 7.6
Answer:
— ¼ = — 0.25
Step-by-step explanation:
![\frac{a + bc}{a - bc} = \frac{ - 12 + 20}{ - 12 - 20} = \frac{8}{ - 32} = - \frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%20%2B%20bc%7D%7Ba%20-%20bc%7D%20%20%3D%20%20%5Cfrac%7B%20-%2012%20%20%2B%2020%7D%7B%20-%2012%20-%2020%7D%20%20%3D%20%20%5Cfrac%7B8%7D%7B%20-%2032%7D%20%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B4%7D%20)
