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:
6.5 = x
Step-by-step explanation:
(x - 4)2 = 5
2*x + 2*-4 = 5
2x - 8 = 5
2x = 13

Answer: OPTION C.
Step-by-step explanation:
The area of a triangle can be calculated with the following formula:

Where "b" is the base of the triangle and "h" is the height of the triangle.
You know that all the triangles that compose the large triangle are equal.
According to the information given in the exercise, the base and the height of any small triangle are:

Therefore, the area of any of them is:

Since there are 4 equal triangles, you need to multiply the area obtained by 4 in order to find the area of the large triangle. This is:

Answer:
The millimeter.
Step-by-step explanation:
The best choice here is the millimeter (mm).
first thing you have to do is find the rate for the bike so you divide 30 by 2 and you get 15 after you do that you make a problem to find the percentage so you take x/100 and 12/15 then you take 12 times 100 and that gives you 1200 then you divide by 15 and get 80. So the answer is 80%
