Answer:
54 - 3n²
Step-by-step explanation:
Square of a number n = n²
Three times the square of n = 3*n² = 3n²
Expression:
54 - 3n²
<u>Given</u><u> </u><u>that</u><u>:</u><u>-</u>
→ 1 sandwich = 2 slices of bread.
→ 1 hiker = 1 sandwich.
→ Then we have to find number of bread slices for n hikers .
→ Number of bread slices for 1 hiker = 2
→ Number of bread slices for 2 hikers = 2 × 2
→ For 3 hikers = 3 × 2
So in similar way
→ Number of bread slices for n hikers = 2×n → 2n
So <u>2</u><u>n</u><u> </u> is the answer.
