Hey, I'll be happy to assist you, but I need a picture or diagram with the measurements of the polygon and the poly itself :)
If the spinner has 6 spots then it’s 3 even and 3 odd therefore it’s C
Ok so the answer is

so we multiply numbers that have the same variable

multiply 2 x 2

then multiply the exponents

multipling like this will look like addition.

so in other words you could do it like this too

now add the exponent with 4

now for the last part

because -3 and 3 added together make 0

I hope this help(it looks complicated but it's very easy and I hope I helped you out)

x 100% = 8700/58 = 150.862069 = 150.86
For the example you gave of m+83, you would just write it out, like "m plus eighty three"
