A trapezium named pqrs with right angles at q&r. PQ equals to 9 cm, PR equals to 4 cm and RS equals to 6 cm. calculate the perimeter of a trapezium

Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Use the data on the dot plot to answer the question. how many people read for more than three hours last week? i'm on a unit test review
