Recursive formula= a(n)=a(1)(n-1)+d
a(n)= 9(n-1)+2
explicit formula= a(n)= a(1)+(n-1)d
a(n)= 9+(n-1)2
12th row= a(12)=9+(12-1)2
a(12)=9+11(2)
a(12)=9+22
a(12)=31
Answer:
Are you sure it is 1830?
Or is it a typo and might 18?
Step-by-step explanation:
Answer:
Angad=6
Malachay=3×6=18
Jim=6
Step-by-step explanation:
Angad,malachy and Jim share =£30 ratio =1:3:1
Let the part of the Angad=X
=3x
=X
So X+3x+X=30
5x=30
X=30/5
X=6
So part of Angad=6
Malachay=3×6=18
Jim=6
Answer:
Step-by-step explanation:
The angles of the triangle are S, M, and L
S+M+L = 180
S ≤ M ≤ L
S = L/2 - 36
Assuming that is a 24 the answer would be 24[10] = 240 but if that is the question 2 and the number is just 4 the answer is just 40
