Please please help!! Solve the system of linear equations using the substitution method shown in picture:)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

vertical=18cm horizontal=18cm hypotenuse=25.5

step-by-step explanation:

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag
