Its 80 because if you find perfect square around the number 80 you'd get
√64 and √81
which would be 8 and 9
Width = Length - 2
Area = L x W
y = x * ( x - 2 )
If the point is ( 2, 0 ): x = 2, y = 0
y = 2 * ( 2 - 2 ) = 2 * 0 = 0 ( area )
Answer:
B ) The area is 0 if the length is 2.
The expression that represents the volume of the composite figure is
. The correct option is the third option 
<h3>Calculating Volume </h3>
From the question, we are to determine the expression that represents the volume of the composite figure
The composite figure consist of a cylinder and a cone
∴ Volume of the composite figure = Volume of the cylinder + Volume of the cone
Volume of a cylinder = 
Where r is the radius
and h is the height of the cylinder
Volume of a cone = 
Where r is the radius
and h is the height of the cone
Consider the composite figure
For the cylinder part
r = 5
h = 13
For the cone part
r = 5
h = 25 - 13 = 12
Thus,
Volume of the composite figure = 
Hence, the expression that represents the volume of the composite figure is
. The correct option is the third option

Answer:
g = 3
Step-by-step explanation:
If you distribute (x+7)(x-4) you get:
x²+3x-28
Compare it to the question:
x²+gx-28
and it becomes obvious that g = 3
Answer:
4/5
Step-by-step explanation:
Played 20 games. Won 16. Both numbers have a 4 in common. divide 16 by 4.. which is 4. Divide 20 by 4... which is 5. That means Tim won 4/5 of the games played.
