Answer
a) \( (4 \times 12) + (4 \times 6) = 4(12 + 6) = 4 \times 18 = 72 \)
b) \( (25 \times 30) - (25 \times 2) = 25(30 - 2) = 25 \times 28 = 700 \)
Solution
Let's apply the inverse of the distributive property to each part of the problem. The inverse distributive property allows us to factor out a common factor from each term in an expression.
### Part a
Given:
\[
(4 \times 12) + (4 \times 6)
\]
**Step 1:** Factor out the common factor \(4\):
\[
4 \times (12 + 6)
\]
**Step 2:** Simplify inside the parentheses:
\[
4 \times 18
\]
**Step 3:** Calculate the final product:
\[
4 \times 18 = 72
\]
**Completed Expression:**
\[
(4 \times 12) + (4 \times 6) = 4(12 + 6) = 4 \times 18 = 72
\]
### Part b
Given:
\[
(25 \times 30) - (25 \times 2)
\]
**Step 1:** Factor out the common factor \(25\):
\[
25 \times (30 - 2)
\]
**Step 2:** Simplify inside the parentheses:
\[
25 \times 28
\]
**Step 3:** Calculate the final product:
\[
25 \times 28 = 700
\]
**Completed Expression:**
\[
(25 \times 30) - (25 \times 2) = 25(30 - 2) = 25 \times 28 = 700
\]

Beyond the Answer
To complete part a, you can rearrange the first equation using the inverse of the distributive property. Here, you're looking to combine \(12\) and \(6\): \( (4 \times 12)+(4 \times 6)=4(12+6)=4 \times 18=72 \). For part b, the equation can similarly be rearranged by using subtraction to combine \(30\) and \(2\): \( (25 \times 30)-(25 \times 2)=25(30-2)=25 \times 28=700 \).
