Use the diagram to answer the following question. If AB=3x-2 and EF=x+1, find AB. Triangle is inside of another triangle with midpoints. Answer is 10. Show steps: 2(3x-2) = 1/2( x+1)2
6x-4 = x+1
-x +4 = -x+4
5x = 5
x = 1
Check: 3(1) - 2 = 1 Should be: 3(4) - 2 = 10
Where is my mistake?

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.
