Answer:
20x + 18
Step-by-step explanation:
We need to use the distributive property, where we essentially take the sum of the product of the outside number with each of the inside terms.
In 7(4x - 2), 7 is the outside number and 4x and -2 are the inside numbers, so:
7(4x - 2) = 7 * 4x + 7 * (-2) = 28x - 14
In 4(2x - 8), 4 is the outside number and 2x and -8 are the inside numbers, so:
4(2x - 8) = 4 * 2x + 4 * (-8) = 8x - 32
Now, we have:
28x - 14 - (8x - 32) = 28x - 14 - 8x + 32 = 20x + 18
The answer is 20x + 18.
Step-by-step explanation:
Step 1: Distribute
[tex]7(4x - 2) - 4(2x - 8)[/tex]
[tex](7 * 4x) + (7 * -2) + (-4 * 2x) + (-4 * -8)[/tex]
[tex](28x) + (-14) + (-8x) + (32)[/tex]
[tex]28x - 14 - 8x + 32[/tex]
Step 2: Combine like terms
[tex]28x - 14 - 8x + 32[/tex]
[tex]20x + 18[/tex]
