Question

6n^2-15=6(5)^2-15 when n = 5​

Answer 1

135 = 135

Explanation:

Substitute 'n' with 5 :

6(5)^2-15 = 6(5)^2-15

Solve :

6 (25) - 15 = 6 (25) - 15

150 - 15 = 150 - 15

135 = 135

Sorry if this isn't what they're asking for! I'm not sure if this was just substituting or if it was asking for true or false :)
