If y = 12, then 3y^2 - 5 =

Step-by-step explanation:

if y = 12

than a/q

= 3(12)² - 5

→ 3 × 144 - 5

= 432 - 5

→ 427 ans

hope this answer helps you dear take care!

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
