Question

Please take a look at the picture. Please write your answer with an explanation.

Answer 1

71

Explanation:

Let's show how this looks at first below. You can walk through my steps to see what new things I do each time.

`13(-3)+40+7(4)-10(-3)+3(4)`

`-39 + 40 + 28 -(-30)+12`

`-39 + 40 + 28 + 30 + 12`

`1+28+30+12`

`29+30+12`

`59+12`

`71`

Hopefully that all makes sense! I first replaced x with -3 and y with -4 in the expression, then multiplied, then simplified by adding or subtracting when needed. If you have any further questions, let me know.
