Answer:
D. -4027
Step-by-step explanation:
After the first two, the integers can be paired so that each pair has a sum of zero.
-2014 +(-2013) +(-2012) + ... (-1) +0 +1 + ... +2012
= -2014 -2013 +(-2012 +2012) +(-2011 +2011) + ... +(-1 +1) +(0)
= -4027 + 0 +0 +0 + ... +0
= -4027

Answer:
y= 2x
Step-by-step explanation:
To figure out what the equation would be you would set up an equation..
16 = 8z
Then you find z
16/8 = 8z/8
2 = z
Now you can set up a variable expression although it isn't necessary
y = zx
Now you plug in the value of z to complete the equation
y= 2x
I hope this is what you wanted!!!
Answer:
<h3>C.) The area of EFGH is always ¹/₂ of the area of the rectangle. </h3>
Step-by-step explanation:
If EG is parallel to the side of the rectangle then lenght of EG is equal to width of rectangle.
If F and H are midpoints of sides of rectangle then FH is parallel to the side of rectangle {wich is perpendicular to the side parallel to EG}. That means the lenght of FH is equal to lenght of rectangle, and FH is perpendicular to EG.
Then FH is sum of hights of triangles EFG and EHG , and the area of EFGH is sum of areas of triangles EFG and EHG .
So the area of the rectangle:
The area of the kite:
No matter the height of the triangles, so no matter the location of the EG
Answer:
3/1 I am not absolutely sure though...
