What expression shows the relationship between the value of any term and n, its position in the sequence for the given sequence? 3, 5, 7, 9, 11, a) 2n b) 2n + 1 c) -n + 3 d) 2n - 2

B.  2n + 1.

Step-by-step explanation:

This is an arithmetic series with first germ 3 and common difference 2.

The nth term (an) = a1 + d(n - 1)

= 3 + 2(n - 1)

= 2n + 3 - 2

= 2n + 1.

angle addition postulate

2x=56

step-by-step explanation:

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
