Answer:
Sum = 13+ 4i Difference = -5 - 8i
Step-by-step explanation:
Given complex number as (4 -2i) and (9 + 6i)
Sum of these complex number is
(4 -2i) + (9 + 6i) = ( 4 +9) + (6i -2i)
= 13 +4i
Difference of these complex number is
(4 -2i) - (9 + 6i) = (4 -9) - (2i +6i)
= -5 - 8i
Hence the sum and Difference of given complex numbers are
Sum = 13+ 4i Difference = -5 - 8i Answer

Answer:
A) 11
Step-by-step explaination:
CE = 2x - 2
CE = CD + DE
= x + 9
Hence it can be said that,
2x - 2 = x + 9
2x - x = 9 + 2
x = 11
Answer:
128.1
Step-by-step explanation:
Since this is rounding to the nearest tenth , we look at the first number after the decimal place it's 0 so we look at the second number after the decimal place which is 9 , this rounds 0 up to 1
The have ordered 36 blue T-shirts.
___________________
How I got it --- So, we take away 16 from 58. You get 42.
________________________________________
So, from then, you know 36 is 6 times as many as 6, right? ( Because 6 x 6 = 36)
___________________________________________________________
So, then, you have ordered 36 blue shirts and 6 white shirts, because 36 + 6 =42.
