Question

Simply the expression: 7x (1-9)?

Answer 1

-56x

Explanation:

Using the order of operations, we know we need to do the stuff inside the parentheses first, so we find that
`1−9` is `-8`. Then we multiply `-8*7x`to get `-56x`,`(-8⋅7=-56)`,

Answer 2

`7xx(1-9)=color(blue)(-56`

Explanation:

If you mean `7xx(1-9)`:

Follow the order of operations as indicated by the acronym PEMDAS:

1. Parentheses/brackets
2. Exponents/powers
3. Multiplication and Division in order from left to right.
4. Addition and Subtraction in order from left to right.

In the expression `7xx(1-9)`, first simplify `(1-9)` to `-8`.

`7xx(-8)`

Now multiply.

`7xx(-8)=-56`
