Design An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Other side is 8 more than three time's the length of the bottom of the triangle. The last side is 5 more than the bottom of the triangle, Write and simplify an expression for the perimeter of the triangle

Two microscope slides are placed horizontally, one on top of the other, with a drop of a dishwashing liquid between them. the gap between the slides is 1 mm. a machine pulls the top slide to the right with a velocity of 0.15 millimeters per second while the bottom slide is held stationary. a stress gage indicates that a shearing stress of 0.5 pa is required to pull the top slide with this velocity. if the dishwashing liquid adheres to both slides during this process, what is the viscosity of the liquid? specify whether your answer is dynamic or kinematic viscosity, and use appropriate units.
