What are the new coordinates of triangle ABC where A (1, -1), B (2, -3), and C (3, -1) after a dilation from the origin with a scale factor of 3? PLEASE HELP

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.

Write the factored form of this trinomial 9x^2+18x-7
