What is the value of x?
(x + 40)
(3x)
o20
o 35
o 60
70

It is twenty because     40+20=60   then 3 times 20 60 as well

hope this helps

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.
