Answer 2

1)=75a (2)=36b (3)=3(x+1) (4)=15a+13

Answer 3

Let's solve each of the equations step by step:

1. 15a × 4: Multiplying 15a by 4, we get: 15a × 4 = 60a

2. 3b × 12: Multiplying 3b by 12, we get: 3b × 12 = 36b

3. 21d - 18d + 3: Combining like terms, we have: 21d - 18d + 3 = 3d + 3

4. 14a + a + 9 + 4: Combining like terms, we have: 14a + a + 9 + 4 = 15a + 13

Therefore:

• 15a × 4 = 60a
• 3b × 12 = 36b
• 21d - 18d + 3 = 3d + 3
• 14a + a + 9 + 4 = 15a + 13
