Answer:
6 > x > -7
Step-by-step explanation:
-8 < x - 1 < 5
+1 + 1 + 1
_____________
-7 < x < 6
The above answer is written in reverse, which is the exact same result.

The answer is 12 but the way you get it is you subtract 400 from 1000 which gives you 600 then you divide 600 by 50 to get 12. So it looks like this 1000-400= 600, 600/50=12. Hope this helps. :)
4ab / 8c
a=8
b=4
c=12
4 x 8 x 4 / 8 x 12 = 192
Hope this helped!!!
Find the area of the parallelogram with vertices k(1, 2, 2), l(1, 5, 3), m(3, 11, 3), and n(3, 8, 2).
Reil [10]
On examining the sides of the parallelogram, we see that the side KL lies in the plane x=1, and the side MN lies in the plane x=3.
Hence the height of the parallelogram is h=(3-1)=2.
The length of side mKL=sqrt((5-2)^2+(3-2)^2)=sqrt(3^2+1^2)=sqrt(10)
The length of side mMN=sqrt((11-8)^2+(3-2)^2)=sqrt(3^2+1^2)=sqrt(10)
Therefore the area of the parallelogram is mKL*h = sqrt(10)*2 = 2sqrt(10)
Answer: Area of parallelogram =
