Answer:
f(n) = 4 +n
Step-by-step explanation:
We assume you want a function that tells the total number of tiles in figure N.
There are 4 triangular tiles in each figure. The number of square tiles is equal to the figure number (n). So, the total number of tiles in figure n is ...
i think its
76/81×80
76=80/81
The answer is 5 + 3x ≤ 50
5 + 3x ≤ 50 - 5
3x ≤ 45
Divide by 3, x = 15
