Question

Which of the following equations will represent a straight line on graph
i)x+1/x =2x ii)2x+5=x2 +5 iii)3x2+5=3x(x+1) iv)None

Answer 1

Step-by-step explanation:

2x+5=x2 = is answer

Perimeter of each tile=12m

Step-by-step explanation:

Given,Length of tile=48m,

Breadth of tile=12m

Number of tiles =64

Area of Hall=Length \times BreadthAreaofHall=Length×Breadth

                            =48m\times 12m48m×12m

 NowArea \ of\ 1\ square\ tile\times Number\ of\ tilesArea of 1 square tile×Number of tiles =Area of Hall

        Area\ of\ 1\ tile\times 64Area of 1 tile×64 =48m\times 12m48m×12m

        Ares of 1 square tiles = \frac{48m\times 12m}{64}6448m×12m

        Area of 1 square tiles=9m

        Area of 1 square tile=3m\times 3m3m×3m

       Side \times SideSide×Side =3m\times 3m3m×3m

      Side= 3m

Now, Perimeter of Square =4\times Side4×Side

                                           =4\times Side4×Side

         Perimeter of Square tile =12m

Hence,Perimeter of each tile=12m.
