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
The Jacksonian Era was characterized by the idea that every citizen was equally important and that all should participate actively in government. The old friends whom Jackson consulted instead of his regular cabinet were called the "kitchen cabinet."
