Radius of a wheel = 13 inch
= 1.08333 ft
circumference of a wheel = 2×pi×r^2
= 2 × (22/7) × 1.08333^2 ft
= 2 × (22/7) × 1.1736 ft
= (44/7)×1.1736 ft
= 51.6384/7 ft
= 7.3769142857 ft
distance covered in one minute = 37 × 60 ft/min
= 2220 ft/min
now, revolution per minute = 2220 / 7.3769142857
= 300.93884
therefore her wheels are making 300.93884 revolutions per minute
12 because if u multiply 3*4 it is 12 and 4*3 is 12 so they both have 12 in common I hope this helps and have a nice day =)
Answer:
Your question is a little unclear. If you are just trying to factor x² + 121, it's prime. (can't be factored using real numbers).
Step-by-step explanation:
The difference of two squares is a special form. a² - b² = (a+b)(a-b).
But, the sum of two squares is prime. a²+ b² cannot be factored.
Answer:
Choice D is correct
