Acarpenter trims a triangular peak of a house with three 7-ft pieces of molding. the carpenter uses 21 ft of molding to trim a second triangular peak. are the two triangles formed congruent? explain.

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

20 solve 2(4 x + 3) < 5 x + 21. a) { x | x < 9} b) { x | x > -5} c) { x | x > -9} d) { x | x < 5}

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
