Answer: 9*10 + 9*11 + 9*12
Step-by-step explanation:
The distributive property of multiplication states that when a number is multiplied by the sum of several numbers, the first number can be distributed to all of those numbers and multiplied by each of them separately.
9(10 + 11 + 12) = 9*10 + 9*11 + 9*12
Answer:
90 + 99 + 108
The 3 number being added should be multiplied by 9.
10 x 9 = 90.
11 x 9 = 99.
12 x 9 = 108.
Therefore, 90 + 99 + 108.
Area = Length x width
