(2m-n)^7
What is the expansion?

Expand using Pascal's triangle.

128m^7−448m^6n+672m^5n^2−560m^4n^3+280m^3n^4−84m^2n^5+14mn^6−n^7

hope i helped :)

to rewrite a literal equation you may need to divide by a number, or by a variable.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
