Use the order of operations to evaluate the expression 4 x (3/4-1/2) + 3 x 6

19

Step-by-step explanation:

19

Step-by-step explanation:

change 1/2 to 2/4

then do 3/4 minus 2/4 which equals 1/4

4 times 1/4 equals 1

3 times 6 equals 18

1 plus 18 equals 19

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.
