Answer:

6. n -8

7. 2 (15+n)

8. 30 + 3n^ 2

Step-by-step explanation:

6 is n-8 because decrease means subtraction

7. Twice the sum means multiplied by 2 sum means addition and a number is the unknown so if we put it together we get 2( 15+n)

8. I'm not sure about 8 but pretty much increased means addition times mean multiplication and twice could be the exponent.

Hope this helps:)

Answer:

6. -8 + n

8. 2[15 + n]

10. 30 + 3n²

Step-by-step explanation:

10. Three times the square of a number → 3n²

Increased by 30 → 30

8. The sum of 15 and a number → 15 + n

Twice the sum → 2[15 + n]

6. A number → n

Decreased by 8 → -8
