Use this simple calcula tor to find the area and perimeter of a rectangle. ... Suppose the length is a = 6 inches and the width is b = 4 inches.
On a phone here and no access to paper but you must first find the midpoint of AC which is the average of the coordinates. The perpendicular bisector will have a gradient that multiplies by AC's gradient to make -1. This will obviously pass through its mid point so as long as you know how to use y=mx+c you should be good.
Answer:
Step-by-step explanation:
7x - 382 = 3x - 161
4x - 382 = -161
4x = 221
x = 55.25
Answer:
c=2r
divide both sides by 2
c/2=r
if you forgot the pi
c=2pir
divide by 2pi
c/(2pi)=r
Step-by-step explanation:
2:1/4=2* 4/1=2*4= 8 is the answer
a: b/c = a * c/b=a*c/b
