Step-by-step explanation:
a square has 4 equal sides. if one of the sides is 40 cm, then all of the other sides are 40 cm as well. to get a perimeter, you add up the lengths of all the sides. if there are 4 sides of 40 cm, you multiply 40 by 4 to get 160, finally add the unit to get 160 cm.
Answer:
2
Step-by-step explanation:
rise over run = y/x
3/1.5= 2
Slope intercept form is y=mx+b
y= m or 2 because that is your slope but now all you need to is find your begin or find the point (3,7) on the graph.
Cross multiply? 9x2=18/3= 6
