account earning 6% per year. How long will it take to double your money?

Ответ:
(5n²+10xn)(2n-3)
Step-by-step explanation:
10n³-15n²+20xn²-30xn
1. Factor by grouping
(10n³-15n²)+(20xn²-30xn)
2. Pull out Greatest Common Factor from each Pair
5n²(2n-3)+10xn(2n-3)
3. Rewrite Factored Expression Properly
(5n²+10xn)(2n-3)
=(5n²+10xn)(2n-3)
ik this doesnt make any sense but hope this helps
