The formula for this sequence is an=2.6+(n-1)*1
recursive formula= an=a(n-1)+1.2
therefore the answer being 6.2
Answer:
x=4 and x= - 5
Step-by-step explanation:
In order to solve this we should re-arrange the equation:
This is equal to:
Then we can seperate this into:
So solving for x in both cases we get
Answer:
13.01 d -2.65
Step-by-step explanation:
3.26d + 9.75d - 2.65
Combine like terms
3.26d + 9.75d - 2.65
13.01 d -2.65
The first question is this: the smallest square is square A, and that is 9 units. and square E is two times that, and so on.
Square A's side length is 9 units and the area is 81.
Square E's side length is 18 and the area is 324.
Square C's side length is 27 and the area is 729.
Square B's side length is 36 and the area is 1,296.
Square D's side length is 45 and the area is 2,025
