Answer:
20 questions
Step-by-step explanation:
Well, 10% of 50 is 5, and 5 x 4 = 20. Another way is 50 x .4
Answer:
5n
Step-by-step explanation:
cost of one helmet = $5
let 'n' be the number of person that is n=1,2,3,4........
note that the value of n is always a natural number
therefore the expression = 5n
where 5 is the cost one helmet
n is the number of persons
Base=(180°-vertex)/2=(180-82)/2=98/2=49°
base angles are 49°
Answer:
n=-7
Step-by-step explanation:
-2(n+2)+6
-2n+2=16
-2n=14
n=-7
First, pull out a factor of
.
Notice that when
(which you can arrive at via the rational root theorem), you have
which means you can pull out a factor of
. Upon dividing you get
The rational root theorem will come in handy again, suggesting that
appears a second time as a root, which means
Now this is more readily factored without having to resort to the rational root theorem. You have
so in fact,
shows up as a root for a third time.
So, you have
Two roots are obvious,
and
(with multiplicity 3). The remaining two are given by
