Which statements are true about the expression 7(2w-4)? check all that apply. -to simplify, distribute 2w to 7 and 4. -7(2w) can be rewritten as 14w. -7(2w-4) can be rewritten as 7(2w)-7(4). -7(2w-4) can be rewritten as 7(). -an equivalent expression is 10w -an equivalent expression is 14w-4 -an equivalent expression is 14w-28

The following are the true statements:
2. 7(2w) can be rewritten as 14w.
3. 7(2w - 4) can be rewritten as 7(2w) - 7(4).
7. An equivalent expression is 14w - 28.

7(2w - 4) can be expanded or simplified by first, drawing a line each from 7 to 2w and from 7 to -4. This will be a reference to you for which you should multiply by. So, 7 has to be multiplied by 2w, and 7 has to be multiplied by -4. Add these 2 multiplications up to give you (7 × 2w) + [7 × (-4)], which is also equal to 7(2w) - 7(4), hence the 3rd statement is right.

The 2nd statement is right because 7(2w) can be rewritten as 7 × 2 × w, which is also 14 × w, or 14w.

The 7th statement is right, since,
7(2w) - 7(4)
= 14w - 7(4)
= 14w - 28

Hope this helps! :)

The following are the true statements:

2. 7(2w) can be rewritten as 14w.

3. 7(2w - 4) can be rewritten as 7(2w) - 7(4).

7. An equivalent expression is 14w - 28.

I just took the test

Sample Response: The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.
