Question 1084292: which equation represents a line that is parallel to the line whose equation is ?
a.1/3x+y=4
b.-1/3x+y=4
c.6x+2y=4
d.-6x+2y=4
the area of rhombus is 100 and the length of its diagonals is 10 what is the length of the other diagonal
a.10
b.20
c.50
d.40

The area of a rhombus is 1/2 the product of the diagonals
100=(1/2)p*q
200=pq
200=10*q
q=20
B.
