15.

A-2b+3c=0 find a^3-8b^3+27c^3

Answer»

$\huge\purple{\bf{ANSWER}}$

$\rm{a - 2b + 3c = 0}$

$\rm{or \: a - 2b = - 3c}$

$\rm{now \: cubing \: on \: both \: sides}$

$\rm{{(a - 2b)}^{3} = {( - 3c)}^{3}}$

$\rm{use \: formula \: \rightarrow{(a - b)}^{3} = {a}^{3} - {b}^{3} - 3ab(a - b)}$

$\rm{ {a}^{3} - {(2b)}^{3} - 3(a)(2b)(a - 2b) = { - 27c}^{3} }$

$\rm{ {a}^{3} - {8b}^{3} - 6ab( - 3c) } = - 27{c}^{3}$

$\rm{ {a}^{3} - {8b}^{3} - 18abc} = - 27{c}^{3}$

$\fbox{\rm{ {a}^{3} - {8b}^{3} + 27{c}^{3} = 18abc}}$

20.	the perimeter of a rectangular swimming pool is 154 M if its length is 2 more than twice its breadth what are the length and breadth of the pool
Answer» Hi ! Here is your answer ! Let the breadth of the pool be x. By the condition , length = 2(breadth) + 2 length = 2(x) + 2 ____________ length = 2x + 2 ____________ The perimeter of the rectangular pool is 154M . We know that , Perimeter of rectangle = 2 ( l + b ) 154 = 2 [ (2x + 2) + (x) ] 154 = 2 [2x + 2 + x] 154 = 2 [3X + 2] 154 = 6X + 4 154 - 4 = 6x 150 = 6x x = 150 / 6 x = 25 Therefore......... Breadth = 25m. length = 2x + 2 length = 2(25) + 2 length = 50 + 2 length = 52m. ________________________ Final Answer : The length & Breadth of the rectangular swimming pool are 52m & 25m respectively . ________________________
