Answer:
Area : 27.5
Perimeter : 20
Step-by-step explanation:
All sides of a regular pentagon have the same length
1 side = 4
4x5 = 20 = Perimeter
Pentagon area formula :
1/4(sqrt(5(5+2sqrt(5)))x)
Plug x in (side length)
27.53
round to nearest tenth
27.5
Answer:
357
Step-by-step explanation:
hello :
note : the n th term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d and A1 the first term
in this exercice : d = -3-(-7) =-7-(-11) = 4 A1 = -11
when : n =93 you have the 93rd term A93
so : A93 = -11 +(93-1)(4)
A93 = 357

Answer:
Step-by-step explanation:
This is the answer because it is subtracted so that you get the answer
8 can go into 10 once, with 2 left over. so it would be 1 2/8, but we simplify to get 1 1/4. you add 7+1 1/4 to get 8 1/4. Hope this helps:)
