What is the factored form of 8x^3 - 27y^3? A. (2x + 3y)(4x^2 - 6xy + 9y^2)

B. (2x – 3y)(4x^2 + 9xy + 6y^2)

C. (2x – 3y)(4x^2 + 6xy + 9y^2)

D. (2x + 3y)(4x^2 - 9xy + 6y^2)

a

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
