3x(3x-2y)
you have to find a common factor between the two numbers. in this case it's three, so you just divide each number by three.
Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v
When given the scale factor, just multiply!
8cm * 2.5 = 20cm per side
2 x - 5y = 13
2 × -1 - 5 × -3 = 13
Answer:
(-1, -3)
