What is the answer to: Find the first three terms: nth term=3n+4?

7, 10, 13

Step-by-step explanation:

1) n = 1:   3(1) + 4 = 3 + 4 = 7

2) n = 2:   3(2) + 4 = 6 + 4 = 10

3) n = 3:   3(3) + 4 = 9 + 4 = 13

x=6 and x=3

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
