Olivia writes an expression that is the sum of three terms. The first term is the product of 2 and the sum of 4 and n.

The second term is 3 squared times n.

The third term is the product of 4 and 2 less than n.

The expression is equal to 30.

What is n?

n= 2

2 x 6= 12

9x2=18

4x0=0

12+18+0=30

(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
