Which expression is equivalent to 2m2-m? (7-m) +6m2? m-m -m +13m2 -m+ m2 om + m2

understand that i don't know the answers

will someone answer his question

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
