Answer:0.8 I think
Step-by-step explanation:
Hello there,
Well we are given with 3(x + 4)² and we need to simplify this expression...
- write out the expression: 3(x + 4)(x + 4)
- then we distribute the parentese: 3(x² +4x +4x +16)
- combine like terms: 3(x² + 8x + 16)
- distribute the 3 in the parentese: 3x² + 24x + 48
So another way to express this would be 3x² + 24x + 48.
Hope I helped,
Amna

Answer:
Correct option: third one -> 12
Step-by-step explanation:
In a polygon with 'n' vertex, we can trace diagonals from one vertex to all vertices, except to the vertex chosen and the two adjacent vertices (because we would have sides and not diagonals), so we would have 'n - 3' diagonals.
If we have a polygon with 15 vertex, the number of diagonals from one vertex is 15 - 3 = 12.
Correct option: third one
