1) 8
2) 6(5x+2y) factor out greatest common factor
3) 10.8 just move over decimal two places to the left.
4) 30t=150? Then t=5kg Im not sure what the last one is asking, but I’m assuming it’s to solve for t.
Answer:
I believe the answer would be 50.714 degrees, I'm not sure how they want you to round that though.
Take the first point (2, 4) a scale factor of 3/2 will move the x coordinate 2 to 2*3/2 = 3 and the y coordinate 4 will be moved to 4*3/2 = 6.
So the image of ( 2, 4) will be ( 3, 6) TH other verices will move in the same fashion.
