Sydnie, Trevor, and Brayden all solved problems on their exam. Grade each of the problems out of 5 points. If their work is 100% correct then they would have a 5/5. If there are errors, determine the error, explain what they did wrong and show how to correct it, then give them the points you think they deserved based on the error they made. ALL PROBLEMS ATTACHED BELOW.
WILL MARK BRAINLISET IF RIGHT
44 POINTS
