<span>A complex number is a number of the form a + bi, where i = and a and b are real numbers. For example, 5 + 3i, - + 4i, 4.2 - 12i, and - - i are all complex numbers. a is called the real part of the complex number and bi is called the imaginary part of the complex number.</span>
Step-by-step explanation:
remember the priorities of the different mathematical operations
1. brackets
2. exponents
3. multiplications and divisions
4. additions and subtractions
so,
14 + 14/7 = 14 + 2 = 16
Answer:
no, no esta bien. la bisectriz es la mitad de 150°, entonces seria 75° y 75°
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
3x-5 = 7
Add 5 to each side
3x-5+5 = 7+5
3x = 12
Divide each side by 3
3x/3 = 12/3
x = 4
