I need help please thank you

Look at triangle wxy what is the length (in centimeters) of the side wy of the triangle?

Which ordered pair is the best estimate for the solution of the system of equations? the graph of the system of equations : y = 3/2x +6 and y=1/4x - 2 , -3) .5, -3.5) , -4) , -3.5)

Find the solution set for this equation: t^2+7t=0 separate the two values with a comma.
