Answer:
12 mph
Step-by-step explanation:
It’s literally 6x2x5 (60 sq ft)
If each spoke reaches from the center of the wheel to its rim, then that means that each spoke is as long as the radius.
To calculate radius:
C=2πr
π=3.14
C=42 inches
42=2(3.14)r
2*3.14=6.28
42=6.28r
Divide 42 by 6.28
42/6.28=6.68
length of each spoke is 6.68 inches.
I'm not smart, but I'm PRETTY sure it's the third one
Both 3x and 9 are a multiple of 3, so we can factor out a 3:
3x + 9 = 3 (x + 3)
