25 POINTS + (dont answer if u don't know it An experimental electrical system has a voltage that can be modeled by V(t) = 0.4t3 + 6.4t2 + 6t, where t represents time in seconds. The resistance in the system also varies and can be modeled by R(t) = t + 1. The current I is related to voltage and resistance by the equation I = V/R
. Write an expression that represents the current in the system.

The expression that represents the current in the system is

Multiplying an even number of negative numbers gives an answer that is choose from:

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below. the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.
