Parallelogram ABCD has diagonals AC and DB that intersect at P. If AP=8x−56, PC=24, PB=36, PD=4y+20, AB=4x+3y, and BC=5x−4y, find the perimeter of this parallelogram. Show your work. Please i need this answered rn for a revision

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
