2x 5-7=16
8x 4-5=19
3x12-5=?
1x10-8= 10

31

Step-by-step explanation:

3*12-5

multiply 3*12,which is 36

then subtract 5 from 36 ,which is 31

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.

my answer is$ 12

step-by-step explanation:

because 15 -2=12
