Multiply: 3m3(2m2 + 3m − 1)
6m6 + 6m4
15m6 − 9m3
6m5 + 9m3 − 3m3
6m5 + 9m4 − 3m3

+ - 3m³.

Step-by-step explanation:

Given :  3m³(2m² + 3m − 1).

To find : Multiply

Solution : We have given 3m³(2m² + 3m − 1).

Distributes 3m³ over (2m² + 3m − 1).

3m³ (2m²) + 3m³ (3m) - 3m³(1).

Same base formula  : *

+ - 3m³.

Therefore, + - 3m³.

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
