Answer:
an=a1+d(n−1) a n = a 1 + d ( n - 1 )
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding −5 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) .
Use Pythagoras:
x² = (8.5)² + (5)²
x = √[(8.5)² + (5)²]
Answer:
19.4 units
Step-by-step explanation:
if perimeter is 2p+2w then the equation is
(2x6.2)+(2x3.5)
12.4+7
19.4 units
hope this helps have a blessed day :)
