I believe v is your coefficient and the degree is 7
8/10 and 48/60 are equivalent because you can see the 48/60 can divide by 8/10 is 6, you just have to see if the larger fraction can divide the smaller one.
I hope this helps you

Answer:
19.73 units.
Step-by-step explanation:
the area of a circle can be found with the equation C=2πr.
first, find the radius of the circle by dividing 6.28 by 2.
6.28/2 = 3.14
next, set up the equation.
C = 2 · π · 3.14
C = 2 · 3.14 · 3.14
C = 19.73
This expression is a good candidate for "factoring by grouping." I note that the first 2 terms and the last 2 terms share a common factor, 2x+1:
8x^3 + 4x^2 - 18x - 9
4x^2 *(2x + 1) -9 (2x+1)
This can be re-written as (2x+1)(4x2-9)
The latter factor is also easily factorable:
(2x+1)(2x-3)(2x+3) (answer)
