Answer:4th answer
Step-by-step explanation:
if width=w
Length =2w+1
Area =length *breadth
36=w(2w+1)
36=2w^2+w
0=2w^2+w-36
You need to know the measurement of the central angle that created the arc (the angle of the two radii) to calculate arc length. The arc length is the fractional amount of the circumference of the circle. The circumference of any circle is found with 2πr 2 π r where r = radius r = r a d i u s .
Answer:A
Step-by-step explanation: The formula for finding volume is LxWxH. 21x 11 is 231, and since one side is 11 so will the other side be, and then you get 2,541 m cubed.
Answer:
Step-by-step explanation:
To do this you would simplify both sides.
For the first one:
(subtract 3 from both sides)
(divide 7 from both sides)
and for the second one:
(add 3 to both sides)
(divide 2 from both sides)
When you graph these they will look like these pictures
