Which side of the original parallelogram corresponds to the y-centimeter side of the enlarged parallelogram?

As we can see from the figure, the "y" side of the parallelogram responds to the larger side of the parallelogram and the "x" side represents the shorter side of the parallelogram.

Since the longer side is 15 cm and "y" corresponds to the longer side, the 15 centimetre side corresponds to the y centimetre side.

“But to answer your question. You can pretty much factor any trinomial with the basic rule. Sometimes youll have to complete the square because the trinomial wont be factorable until then. The main use of factoring trinomials tho is to find the value of x. Most trinomials usually equal 0 when youre in high school math. So you factor and make both equations equal 0. Another case where you might need to factor is when you are dividing a trinomial by a binomial. You can factor the numerator and denominator and potentially cross out two terms that divide to equal 1. Overall, its really helpful.”
