felix has a bookcase that is 2 feet taller than it is wide the expression 4x+2 (x+2)represents the total length of a board that can be cut for the top bottom 2 shelves and 2 sides of the bookcase what does x represent in this expression

x represents the width of the bookcase.

Step-by-step explanation:

Let w be the width of the bookcase.

Bookcase that is 2 feet taller than it is width.

Length = w+2 feet.

Length of a board that can be cut for the top bottom 2 shelves and 2 sides of the bookcase.

Top and bottom = w+w = 2w

2 shelves = w+w = 2w

2 sides of the bookcase = 2(w+2)

Total length of a board that can be cut for the top bottom 2 shelves and 2 sides of the bookcase is

   ...(i)

It is given that total length of a board that can be cut for the top bottom 2 shelves and 2 sides of the bookcase is

   ...(ii)

From (i) and (ii) we get

Therefore, x represents the width of the bookcase.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

2425
