<u>Step-By-Step Solution for Part 1:</u>

3(4p + 2) = 12p + 6
=> (3 x 4p) + (3 x 2) = 12p + 6
=> 12p + 6 = 12p + 6

Answer: Equivalent

<u>Step-By-Step Solution for Part 2:</u>

r + r = 2r
=> 2r = 2r

Answer: Equivalent

<u>Step-By-Step Solution for Part 3:</u>

2y + z² = y x y + z + z
=> 2y + z² = y² + 2z

<u>[Replacing y as 2 and z as 3]</u>

=> 2(2) + (3)² = (2)² + 2(3)
=> 4 + 9 = 4 + 6
=> 13 ≠ 10

Answer: Not Equivalent

<u>Step-By-Step Solution for Part 4:</u>

15n + 5 = 5(3n + 1)

=> 15n + 5 = (5 x 3n) + (5 x 1)

=> 15n + 5 = 15n + 5

Answer: Equivalent
