The side lengths of two triangles are shown. Represent the perimeter of each triangle with an expression in simplest form. Which triangle has a greater perimeter if x=4? Will this be true if x=5? Justify your response.

a) Triangle A: 4x + 3, Triangle B: 8x + 2, Triangle B has a greater perimeter for x=4, and it will still be true for x=5.
b) Triangle A: 8x + 2, Triangle B: 4x + 3, Triangle A has a greater perimeter for x=4, and it will still be true for x=5.
c) Triangle A: 8x + 2, Triangle B: 4x + 3, Triangle B has a greater perimeter for x=4, but it won't be true for x=5.
d) Triangle A: 4x + 3, Triangle B: 8x + 2, Triangle A has a greater perimeter for x=4, but it won't be true for x=5.
