Evaluate 2(3n−9) when n=13. 2(3n−9) =2(3⋅ −9) =2( −9) =2( ) =

Steps to solve:

2(3n - 9); n = 13

~Substitute

2(3(13) - 9)

~Simplify

2(39 - 9)

~Subtract

2(30)

~Multiply

60

Best of Luck!

Step-by-step explanation:

The value of n is 13.

Solving for brackets,

Multiplying,

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
