Which number from the set {5, 10, 15, 18} makes the equation true? 2x + 3(x + 4) = 37
A) 5
B) 10
C) 15
D) 18

5

Step-by-step explanation:

2x+3(x+4)=37

2(5)+3(5+4)=37

10+3(9)=37

10+27=37

37=37

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.
