Consider the sequence:

3, 8, 13, 18, 23,

the recursive formula for this sequence is:

latex: a_n=a_{n-1}+5a n = a n − 1 + 5.

in complete sentences, explain what latex: a_na n, latex: a_{n-1}a n − 1, and the 5 represent in the formula. find latex: a_8a 8. what do you need to know in order to find latex: a_8a 8?

The recursive formula

means that the current element () is written in terms of the term immediately before ().

In order to get , you have to add 5 to the previous term . In other words, every term is 5 more than its predecessor.

So, if we want the 8th term, we can keep adding 5 until we get there:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
