Hello! The question simplified is 4x + 14. This is because when you have a negative symbol in front of the numbers you need to distribute, you change the numbers inside into the opposites, and then multiply by -1. When you do this, you get 3 + 4x + 5 + 6. When you combine like terms, you get 4x + 14. The answer is B: 4x + 14.

A. and B. are the legs in a triangle and C. is the hypotenuse. If you have A. and C. but not B, you square A. and C. and subtract C. from A. Then, after you get the number, you square that number, which will be√(2304), which makes 48.
