hope this helps
Answer:
10n^5 +11n^3 -6
Step-by-step explanation:
Add like terms:
(-3+3n^5+6n^3)+(7n^5+5n^3-3)
= n^5(3 +7) +n^3(6 +5) +(-3 -3)
= 10n^5 +11n^3 -6
and -
19.8
Since 3.3*6 is 19.8.
c...........................
n-5
If n is the number, then the equation is n-5 because the number decreases by 5 each time.
