  x +1                 x^2 +5x +4              x +1                 (x +1)(x +4) 
---------------- / ---------------------- = ----------------- / ----------------------- = 
x^2 +x -6             x +4                    (x +3)(x -2)               x +4

       x +1                  1                     1
= ---------------- * ----------- = ------------------

a rectangular wall with a length of 10x and width of 20 x has a rectangular doorway with a length of 5x and a width of 2x. What
Shtirlitz [24]

Answer:

∴ The the surface area of the wall is 190x^{2} \ square\ unit.

Step-by-step explanation:

Given that,

                 The length of rectangular wall is 10x.

                 The width of rectangular wall is 20x.

                 The length of doorway is 5x.

                 The width of doorway is 2x.

and, we have to find the surface area of rectangular wall.

Now,

The length of rectangular wall is 10x.

The width of rectangular wall is 20x.

∴ Total surface area of a rectangular wall = Length\ of\ wall\times Width\ of\ wall

                                                                     = 10x\times 20x

                                                                     = 200x^{2} \ square\ unit

Total surface area of a rectangular wall is 200x^{2} \ square\ unit.

Again, The length of doorway is 5x.

           The width of doorway is 2x.

∴Total surface area of doorway =Lenght\ of\ doorway\times Width\ of\ doorway

                                                     =5x\times 2x

                                                     =10x^{2} \ square\ unit

Total surface area of doorway is 10x^{2} \ square\ unit.

∴The remaining surface area of a rectangular wall is = 200x^{2} -10x^{2}                                                                                                        

                                                                                           =190x^{2} \ square\ unit

∴ The the surface area of the wall is 190x^{2} \ square\ unit.

Find the length of each arc.
lukranit [14]

Answer:

34/3 pi

Step-by-step explanation:

We can find the arc length by

s = r theta where theta is in radians

Change 255 to radians

255 * pi/180 = 17/12 pi

s = 8 * 17/12 pi

s = 34/3 pi
