Answer:

35 degrees

Step-by-step explanation:

The law of reflection states that the angle of reflection equals the angle of incidence, or

(у-4) (3x+5y-2) How do I multiply the following expression?<br>​
muminat

Answer:

3xy + 5y^{2}  - 12x - 22y + 8

Step-by-step explanation:

You will use the FOIL method, which is very similar to the distributive property.

In order to do multiply correctly, multiply the y by 3x, 5y, and -2. You should get:

3xy + 5y^{2}  - 2y

Then multiply the -4 by 3x, 5y, and -2 where you should get:

- 12x - 20y + 8

By using the foil method, you got rid of the parentheses. Now you can simply combine like terms and get your final answer:

3xy + 5y^{2} - 12x - 22y + 8

I hope this helps you!
