Answer: D
Step-by-step explanation:
If Joe orders 2 chicken dinners and 3 sides for $34.50, then you have to multiply 3.50 by 3 to get the ammount that the dinners cost.
3.50x3 = 10.50
Next, you have to subtract 10.50 from 34.50 to get the cost of just the 2 dinners.
34.50 - 10.50 = 24.00
Now, divide 24 by 2 to get the cost for 1 dinner.
24/2 = 12
Since Brody ordered 2 sides, you have to subtract 3.50x2 = 7 from 43 to get the total of his dinners.
43 - 7 = 36.
Now we can check our answer. Since 1 dinner costs $12, we can multiply 12 by 3 to get 36, which is the exact same number as the one we just figured out. So, each side costs 3.50.
(You can also multiply 12 by 3.50 to get 43, which was the total cost of Brody's order.)

Answer:
(5x + -4y)(3x + 7y) = 0
Multiply (5x + -4y) * (3x + 7y)
(5x * (3x + 7y) + -4y * (3x + 7y)) = 0
((3x * 5x + 7y * 5x) + -4y * (3x + 7y)) = 0
Reorder the terms:
((35xy + 15x2) + -4y * (3x + 7y)) = 0
((35xy + 15x2) + -4y * (3x + 7y)) = 0
(35xy + 15x2 + (3x * -4y + 7y * -4y)) = 0
(35xy + 15x2 + (-12xy + -28y2)) = 0
Reorder the terms:
(35xy + -12xy + 15x2 + -28y2) = 0
Combine like terms: 35xy + -12xy = 23xy
(23xy + 15x2 + -28y2) = 0
Solving
23xy + 15x2 + -28y2 = 0
Solving for variable 'x'.
Factor a trinomial.
(5x + -4y)(3x + 7y) = 0
