In spencer is guarding the number of rosebushes is seven less than 1.5 times the number of carnation bushes if the number of carnation but it is see you then expression represents the number of rosebushes is

1.5c - 7 because the it says 7 less than, so subtraction, then it says 1.5 times a number so just any letter i chose c for carnation bushes.  

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

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
