Answer:
80ab + 9b
Step-by-step explanation:
Step 1: 14 x 5 + 2ab x 5 + 4b x 2 + b
Then......
Multiple the numbers: 14 x 5 = 70
Step 2: = 70ab + 2 x 5ab + 4 x 2b + b
Then......
Multiple the numbers: 2 x 5 = 10
Step 3: = 70ab + 10ab + 4 x 2b + b
Then......
Multiple the numbers: 4 x 2 = 8
Step 4: = 70 ab + 10ab + 8b + b
Then......
Add similar elements: 70ab + 10ab = 80ab
Step 5: = 80ab + 8b + b
Then......
Add similar elements: 8b + b = 96
80ab + 9b
