Answer:

X= 12

Step-by-step explanation:

30/25=1.2

25x1.2=30

10x1.2=12

Answer:

x = 15

Step-by-step explanation:

Both figures are the same shape, but in different sizes. The side on Figure A is 5 bigger than the side on Figure B. (30 - 25 = 5) That would mean that it will follow the same rule for the other side. (15 - 10 = 5)

Hope this helps!
