Answer:
6:10 is the only ratio equivalent to 3:5
Step-by-step explanation:
its not the first one because 5 goes into 30 6 times and 3*6=18 not 13
4:15 isn't possible either because 5 goes into 15 3 times and 3*3=9 not 4
the last one is correct because 3*2=6 and 5*2=10
6:10
3:5 is equivalent to 6:10 because you multiply both 3 and 5 by 2 and you get 6:10. every thing else is wrong
Start with 2. Then subtract from it (2x - 7)^2.
2 - (2x - 7)^2
