Question 1178613

if {{{2x/3}}},{{{5/(x-3)}}} and {{{7/(x+2)}}} are the three sides of a triangle, the expression that will represent the perimeter of the triangle is




{{{2x/3+5/(x-3)+7/(x+2)}}}......common denominator


{{{2x(x-3)(x+2)+5*3(x+2)+7*3(x-3))/(3(x+2)(x-3))}}}


{{{(2x^3-2x^2-12x+15x+30+21x-63)/(3(x+2)(x-3))}}}


{{{(2x^3-2x^2+24x-33)/(3(x+2)(x-3))}}}


{{{(2x^3-2x^2+24x-33)/(3(x+2)(x-3))}}}-> the expression that will represent the perimeter of the triangle
