6w^3 - 13 the gcf ? or is this a prime?

Me figure out the process to determine x you appreciate it : )

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?
