Hello :
<span>the nth term in a geometric sequence where is ;
an = a1 ×qn .... q : common ratio a1 the first term
exempl :
C) an = 2×3^n-1
an =2×3^n ×3^-1
an =(2/3)×3^n
a1 = 2/3 and q= 3
same method for : D
</span>
The first answer is 2.5 and I don’t know the last two sorry
Answer:
Step-by-step explanation:
Given,
Length (l) = 2(7z + 3) = 14z + 6
Breadth (b) = 5z
Now,
Perimeter of rectangle (P) = 2(l + b)
=2(14z + 6 + 5z)
=2(19z + 6)
=38z + 12
