Answer:
5y^2(4y^4 - 3y^2 +8)
Step-by-step explanation:
20y^6 - 15y^4 + 40y^2
5y^2(4y^4 - 3y^2 +8)
Don't really need to post the options to know what the expression(s) should look like.
"Sum of" tells you its addition and because it's addition the order of the two terms (the 3 and the N) don't matter.
Your correct expressions are:
3 + n
or
n + 3
