Answer:
Step-by-step explanation:
(4 - 7i) + (1 - 2i)
4 - 7i = 1 - 2i
collect like terms
4 - 1 = -7i + 2
3 = -5i
I no learn yet. buttttttt what ever I don't care
To find the perfect square needed, you take the "middle" value and half it, then square it. so in this case, take -6, half it into 3, and square it to get 9. you'll be adding 9 to both sides
Before you begin, familiarize yourself and keep in mind the
order of operations- PEMDAS (parenthesis, exponents, multiplication, division,
addition, subtraction). You must do all math problems using this.
17. Add all the
numerators since they are like-terms. 12/3 – then simplify it – 4.
18. Do the inner most
parenthesis first, add the numerators – 3/5. To multiply a fraction and a whole
number, multiply the numerator and the whole number, and then simplify – 15/5,
3, then divide 15 by 3 – and your answer
is 5.
19. Parenthesis first – 10/6. Then multiply the numerator
and the whole number and simplify – 120/6 – 20.
20. Parenthesis – 4.2 – multiply by 8 – 33.6.
21. Parenthesis – 4 – multiply by 3.6 – 14.4.
22. PEMDAS, so division goes before subtraction – 8.4.
Try the rest for yourself; that’s the only way you’ll learn.
