Answer:
![k=\frac{-cp+4r}{p}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B-cp%2B4r%7D%7Bp%7D)
Step-by-step explanation:
![r=p/4(c+k)](https://tex.z-dn.net/?f=r%3Dp%2F4%28c%2Bk%29)
![\frac{r}{p/4} =c+k](https://tex.z-dn.net/?f=%5Cfrac%7Br%7D%7Bp%2F4%7D%20%3Dc%2Bk)
![\frac{r}{p/4} -c=k](https://tex.z-dn.net/?f=%5Cfrac%7Br%7D%7Bp%2F4%7D%20-c%3Dk)
![-cp+4r=kp](https://tex.z-dn.net/?f=-cp%2B4r%3Dkp)
![\frac{-cp+4r}{p} =k](https://tex.z-dn.net/?f=%5Cfrac%7B-cp%2B4r%7D%7Bp%7D%20%3Dk)
Answer:
B
Step-by-step explanation:
Given 2 sides of a triangle then the third side is in the range
difference of 2 sides < AB < sum of 2 sides , that is
54 - 27 < AB < 54 + 27
27 < AB < 81 → B
y = mx +b
y = -2x +0
the y intercept is 0
so one point is (0,0)
the slope is -2
we go down 2 to the right 1 (1,-2)
we now have 2 points
2 points make a line
I think it’s the last one
Answer:
2x^2 - 8x + 6
Step-by-step explanation:
2x*x+(-3x*2x)+(x*(-2))+6=
2x^2-8x+6
