Answer:
Step-by-step explanation:
(2n³ - 3n⁴ + 7n) - (n³ - 8n⁴ - 7n) = 2n³ - 3n⁴ + 7n - n³ + 8n⁴ + 7n
{Here -1 is distributed }
= <u>2n³ - n³</u> -<u> 3n⁴ + 8n</u>⁴ +<u> 7n + 7n</u>
{Combine like terms}
= n³ + 5n⁴ + 14n
The answer is: n^3 + 5n^4 + 14n
sorry di pa namin yan napapag aralan..
it's B
2/8 = 1/4 = 0.25
1/2=0.5
0.5>0.25
so (1/2)>(1/4)
