Answer:

71

Step-by-step 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.

Answer:

25a^{2}+5ab+\frac{b^{2} }{4}

Step-by-step explanation:
