Answer:
139
Step-by-step explanation:
first solve for x
3x + 2 = 0
3x = -2
3x/3 = -2/3
x = -0.66
and then add your numbers together
112 + 27 + (-0.66) = 138
138 rounded is 139
Answer: The given expression "2 divided by the quantity of 2 plus 5i" can be translated as 2/(2+5i). Simplifying expressions aim is to simplify it into its simplest form. Since i = √-1 substitute it into the expression.
2/(2+5√-1)
then multiply it by 2-5√-1 on the numerator and denominator and we have
[2(2 - 5√-1)] / [4 - 25(1)]
(4-10√-1)/(-21)

Answer: The answer is C) 44 units.
Step-by-step explanation:
The question is asking for perimeter, not area. Instead of multiplying 9*13 to get area, we need to add the sides together. If the width on one side is 13, so is the witdh on the other side. This rule applies to the length as well.
9 + 9 + 13 + 13 = 44, so the perimieter of the rectangle is 44 units.
Hey there!
Let's solve this problem step by step!
![(12b^{2} +1)-(-8b^{2} )](https://tex.z-dn.net/?f=%20%2812b%5E%7B2%7D%20%2B1%29-%28-8b%5E%7B2%7D%20%29%20)
Remove the parenthesis between the first sum.
![12b^{2} +1-(-8b^{2} )](https://tex.z-dn.net/?f=%2012b%5E%7B2%7D%20%2B1-%28-8b%5E%7B2%7D%20%29%20)
Work out the parenthesis that are left. Remember that multiplying a negative by a negative makes you end up with a positive outcome.
![12b^{2} +1+8b^{2}](https://tex.z-dn.net/?f=%2012b%5E%7B2%7D%20%2B1%2B8b%5E%7B2%7D%20)
And finally collect the terms. We can only add the
. We then find the following solution
![20b^{2} +1](https://tex.z-dn.net/?f=%2020b%5E%7B2%7D%20%2B1%20)
