Not as old as those found in deeper layers
Answer:
The Homestead act of 1862 was passed, giving away land on the condition that settlers would develop them.
Explanation:
X=-3 , y=-2
You have to plug it in to double check but make you know what's parallel and perpendicular.
Since this is a square you can set 3x+20=5x then you can solve for x.
Subtract 3x from both sides:
3x-3x+20=5x-3x
20=2x
Divide both sides by 2
20/2=2x/2
10=x
Hope this helps.
