Answer:
No Solutions
Step-by-step explanation:
First to complete the square, it will need to look something like
a^2+2ab+b^2
so in order to get that we can see that 4n^2+8n seems to be missing a piece.
a is the square root of 4n^2 which is 2n.
8n/2n=4
4/2=2
b=2
so now add 2 to both sides of the equation so now it's
4n^2+8n+4=-13
rewrite as (2n+2)^2=-13
Now you see a negative number as the result of a exponent.
A number squared will never be negative.
Therefore the answer is

Answer:
Option B. 24/25
Step-by-step explanation:
we know that
In the right triangle DEF
∠D+∠E=90° -----> by complementary angles
so
sin(D)=cos(E)
we have
sin(D)=24/25
therefore
cos(E)=24/25
