Answer: 9(7y+5)-4(-6y-1) simplifies to 87y + 49.
6(5f+4)-2(6f-4) simplifies to 18f + 32
Explanation:
To simplify the expressions:
9(7y+5)-4(-6y-1)
Distribute the 9 and -4:
63y + 45 + 24y + 4
Combine like terms:
87y + 49
Therefore, 9(7y+5)-4(-6y-1) simplifies to 87y + 49.
6(5f+4)-2(6f-4)
Distribute the 6 and -2:
30f + 24 - 12f + 8
Combine like terms:
18f + 32
Therefore, 6(5f+4)-2(6f-4) simplifies to 18f + 32
