Answer:
20 feet
Step-by-step explanation:
s= side
P= 4s
I our case, s is 4, so 4*5 is 20.
Hence,
P=20
Hope this helps!
(P+9s+21)/3
hello :
P/3 + (3s + 7) = P/3 + 3(3s + 7)/3 = (P+9s+21)/3
6^8
6^4 * 6^4
We know that a^b * a^c = a^(b+c)
6^4 * 6^4 = 6^(4+4) = 6^8
84
The mean is calculated as
mean = , then
= 21 ( multiply both sides by 4 )
sum = 84
