Answer:
4x - 2y = -8--------equation 1
y = 2x + 4
or, -2x+y=4---------equation 2
multiply equation 2 by 2 and solving equation 1and2 we get,
4x - 2y = -8
-4x+2y=8
---------------=
impossible

Answer:the perimeter of the rectangle =A) (−14w+14v) centimeters
Step-by-step explanation:
Step 1
The perimeter of a Rectangle is given as 2 (l+ w)
If Length = 2v+3w centimeters.
and width =5v-10wcentimeters
Then Perimeter =2 (2v+3w + 5v-10w)
Perimeter=2(7v -7w)
Perimeter= 14v - 14w or can be written as -14w +14v
