Step-by-step explanation:
Answer: x=12
Step-by-step explanation:
5x-15=2x+21(AIA)
3x-15=21
3x=36
x=12
I just had a test on this lol perfect timing. Anyways the answer would be 3 times bigger bc the circumference of a circle with the radius of 3 is 6pi and the circumference of a circle with the radius of 1 is 2pi which makes the first circle 3 times bigger
I'd say that the relationship between y and x is that they're both equivalent to each other, since -3 = -3.
