3. The diagram shows a square.
(7x + 3) cm
Find the length of the side of the square.
3cm
(5x + 8) cm

Step-by-step explanation:

The four sides of a square are equal.

7x + 3 = 5x + 8             Subtract 5x from both sides

7x - 5x + 3 = 8              Combine the left

2x + 3 = 8                     Subtract 3 from both sides

2x = 8-3                        Combine the right

2x = 5                           Divide by 2

x = 5/2

x = 2.5

That is not quite the answer

Side = 7x + 3

Side = 7*2.5 + 3

Side = 17.5 + 3

Side = 20.5

step-by-step explanation:

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
