<u>Given </u><u>:</u><u>-</u><u> </u>

  • C is the midpoint of BD .
  • BC = x + 7
  • CD = 8x

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • Value of BD ( correct )

<u>Answer</u><u> </u><u>:</u><u>-</u><u> </u>

As C is the midpoint , we can say that the line is BCD . So that ,

  • BC + CD = BD

Substitute the values ,

  • ( x+7 ) + 8x = BD
  • BD = x + 8x + 7
  • BD = 9x + 7 .

<u>Hence</u><u> the</u><u> </u><u>value</u><u> of</u><u> </u><u>BD </u><u>is </u><u>9</u><u>x</u><u> </u><u>+</u><u> </u><u>7</u><u> </u><u>.</u>

Between which two consecutive integers does √53 lie?
GREYUIT [131]
Hey there :)

We can solve 2 ways: With a calculator and Without

With:
√53 = 7.28

Therefore this lies between 7 and 8

Without:
6² and 7² = 36 and 49
Still, the values are less than 53, which means √53 does not lie between 6 and 7

7² and 8² = 49 and 64
53 is between both values, therefore √53 lies between 7 and 8

Your answer will be option B) 7 and 8
