-3x^3 (-2x^2+4x-3)

A. 6x^6- 12x^3+ 9
B. -5x^5+ x^4- 6x^3
C. 6x^5- 12x^4+ 9x^3
D. -6x^6- 12x^4+ 9x^3

C) 6x^5-12x^4+9x^3

Step-by-step explanation:

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

-3x^3*(-2x^2)-3x^3*4x-3x^3*(-3)=

6x^5-12x^4+9x^3

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
