Computer science Hey! So I have a project to do however I used a reference for coding and now I have to write a written response would it be considered plagiarizing if I mention the code I used for reference? (I already gave credit to the creator)

Which expression is equivalent to 2x^2+2x-4/2x^2-4x+2

Use the elimination method to find the solution to the system of equations. 2x - 3y = -9 -x + 3y = 6

9.4.34  question   to estimate the height of a stone  figure, an observer holds a small square up to her eyes and walks backward from the figure. she stops when the bottom of the figure aligns with the bottom edge of the  square, and when the top of the figure aligns with the top edge of the square. her eye level is 1.811.81 m from the ground. she is 3.703.70 m from the figure. what is the height of the figure to the nearest hundredth of a  meter?
