The sides of a rectangle are 3t - 2 and 5t + 7. write an expression for the perimeter of the rectangle.
just so you know this is about factoring.

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.

Which value of y will make the inequality y< -1 false?

How can constraints be used to model a real-world situation?
