Answer:
6x = 42
Step-by-step explanation:
The formula to find the area of a rectangle is
. Since we have a value for the width, we simply need to find what to multiply to 6 to get 42.
Let x = length
6x = 42
We then divide both sides by 6 to find the value of x.


So we know the length is 7.
To check the answer we substitute x with 7.


Answer:
xy = 28
Step-by-step explanation:
The formula for inverse variation is
xy =k
If y = 4 and x = 7
4*7 = k
28 = k
The equation is xy = 28
Im not really sure but i thinki think it is
XY=WZ=28. (Opposite sides of a parallelogram are equal)
Angle Z=angle C=105
=>angle Y=180-105=75. (Co-interior angles are supplementary)
Hope this helps u...!!
