The correct answer is the first option, which is:
(–7 + i) + 7i = –7 + (i + 7i)
The explanation is shown below:
1. By definition, in the associate property of addition you summ the number by grouping them with parenthesis, without matter where you use those parenthesis.
2. Therefore, as you can see, you can obtain the result of the addition by agruping the numbers <span>(–7 + i) + 7i or –7 + (i + 7i)</span> .
Answer: The second one
Step-by-step explanation:
Answer:
-11
Step-by-step explanation:
Firstly simplify your expression...by dealing with the brackets
; -k - 7k + 6n + 3n
;then substitute with the given values into your expression,
;-(-2) -7(-2) + 6(-3) + 3(-3)
; 2 + 14 - 18 - 9
; 16 - 27
;Hence the answer is -11
;
(a)^2+(b+22)^2=(c+44)^2. Then just solve for the variables
