Hi everybody!
i hope you are doing well.
i really need on these two algebra 1 questions. i've been stuck for a whole day and i would appreciate it if it could be explained..
1. bradley has 3 square pieces of cardboard with each side equal to x units. for each piece, he does something different to it according to each part below:
part a: bradley pasted rectangular strips along two adjacent sides of the cardboard to increase its length and width by y units each. what will be the change in the area of the piece of cardboard? show your work.
part b: bradley cut off rectangular strips from two adjacent sides of the cardboard to decrease its length and width by y units each. what will be the change in the area of the piece of cardboard? show your work.
part c: bradley cut off a strip from one side of the cardboard and pasted the strip on an adjacent side of the cardboard to increase its length by y units and decrease its width by y units. what will be the change in the area of the cardboard? show your work.
2. part a: divide (10x^4y^3 + 5x^3y^2 - 15x^2y - 25x^2y^4) by -5x^2y. show your work, and justify each step.
part b: how would your answer in part a be affected if the x^2 variable in the denominator was just an x?
part c: what is the degree and classification of the polynomial you got in part a?
even if you only have time to answer one of the questions, it would really .
you so much!
