Step-by-step explanation:
Answer:
$180
Step-by-step explanation:
1. Find the perimeter: 2w + 2L
2(4) = 8 + 2(5) = 10
8 + 10 = 18 feet of fencing
2. multiply the cost per foot (10) by the number of feet (18)
10*18 = 180
Answer:
21
Step-by-step explanation:
Note that n! = n(n - 1)(n - 2) ..... × 3 × 2 × 1, thus
7! = 7 × 6 × 5 × 4 × 3 × 2 × 1
5! = 5 × 4 × 3 × 2 × 1
2! = 2 × 1
Hence
cancel 5 × 4 × 3 × 2 × 1 on numerator/ denominator, leaving
= 
= 21
Answer:
B. 5
Step-by-step explanation:
