We are given that
An ion has a charge of +7
and a neutral has charge always 0
so, change is charge = ion charge - neutral change
so, we can plug values
change is charge = +7 -0
change is charge = 7
so, option-C..................Answer
Answer:
Step-by-step explanation:
15,878,144
Step-by-step explanation:
To find the sum of the measures of the intereor angles of each convex polygon
we using formula
<h3>#4</h3>
we can put the value of x is 54
then,
<h3>#5</h3>
we can put the value of x is 19
then,
#6
we can put the value of x is 292
then,
- =》 52200°
#7
we can put the value of x is 5
then ,
- =》 540°
54x89=4806
123x85=10,455
64x15=960
264x14=3,696
2n + 1 , 2n + 3 , 2n + 5
____________________________
( 2n + 5 ) + ( 2n + 3 ) = 5 × ( 2n + 1 ) - 15
4n + 8 = 10n + 5 - 15
4n + 8 = 10n - 10
Add both sides 10
4n + 8 + 10 = 10n - 10 + 10
4n + 18 = 10n
Subtract both sides 4n
4n - 4n + 18 = 10n - 4n
18 = 6n
Divide both sides by 6
18 ÷ 6 = 6n ÷ 6
n = 3
_________________________________
Thus that three numbers are :
2(3) + 1 , 2(3) + 3 , 2(3) + 5
6 + 1 , 6 + 3 , 6 + 5
7 , 9 , 11
And we're done ....
