find an equation of the line that has a y intercept of -2 and is perpendicular to the graph of the line x-2y=5.

x-2y=5 into y=mx+b

-2y=-x+5

-2y/-2=-x/-2+5/-2

y=1/2x+-5/2

y=-2x-2

Step-by-step explanation: i think im right  

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

answer: add the !
