I didn't know which equation you were asking about, so I solved for both of them. I hope this helps!

Answer:

Step-by-step explanation:
Combine like terms (terms with the same exponent).

"Standard form" means to list terms so the exponents go from high to low (descending order).
For eight loop, multiply it by 3 to get the whole length of loop
8 x 3 = 24 inches
Since 12 inches is equivalent to 1 feet, convert that
24 inches * (1 feet / 12 inches) = 2 feet
I think it is 4.5 miles per hour
Idk this answer because no triangles are shaded.
