Question

I need to know the answer

Answer 1

Answer:

2n³ + 4

Step-by-step explanation:

Take off the parentheses (brackets) because there is nothing to multiply with it :

5 + 5n³ - 1 - 3n³

Now arrange the equation :

5n³ - 3n³ + 5 - 1

Subtract all the same variables :

5n³ - 3n³ = 2n³

5 - 1 = 4

Now arrange the equation again :

2n³ + 4
