The completely factored form of 2d4 + 6d3 − 18d2 − 54d is

2d(d + 3)^2(d - 3)

Step-by-step explanation:

2d^4 + 6d^3 - 18d^2 - 54d

= 2d^3(d + 3) - 18d(d + 3)

= (2d^3 - 18d)(d + 3)

= 2d (d^2 - 9)(d + 3)

= 2d(d + 3)^2(d - 3)

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.

wth is with the little mtn top and what are you talking about like fix your words and accually make sence with them and i like was in a completly different question like three times like it seems like your ilitteret
