Multiplying a Multidigit Number by a Single-Digit Number Using Distributive Property

To calculate the values of the given expressions using the distributive property of multiplication, we can break down each expression into smaller parts and then perform the necessary calculations. Let's go through each expression step by step:

1. (90 + 3) * 5: - First, we add 90 and 3, which gives us 93. - Then, we multiply 93 by 5, resulting in 465.

2. (60 + 3) * 3: - Adding 60 and 3 gives us 63. - Multiplying 63 by 3 gives us 189.

3. (40 + 3) * 4: - Adding 40 and 3 gives us 43. - Multiplying 43 by 4 gives us 172.

4. (30 + 2) * 43: - Adding 30 and 2 gives us 32. - Multiplying 32 by 43 gives us 1,376.

5. (9 + 8) * 5: - Adding 9 and 8 gives us 17. - Multiplying 17 by 5 gives us 85.

6. (8 + 3) * 2: - Adding 8 and 3 gives us 11. - Multiplying 11 by 2 gives us 22.

Equivalent Expressions

Now, let's consider which expressions have the same value:

- The expressions (90 + 3) * 5 and (9 + 8) * 5 both equal 465. - The expressions (60 + 3) * 3 and (8 + 3) * 2 both equal 189. - The expressions (40 + 3) * 4 and (30 + 2) * 43 both equal 172.

Written Form

To summarize, the values of the given expressions using the distributive property of multiplication are:

- (90 + 3) * 5 = 465 - (60 + 3) * 3 = 189 - (40 + 3) * 4 = 172 - (30 + 2) * 43 = 1,376 - (9 + 8) * 5 = 85 - (8 + 3) * 2 = 22
