the real solutions for the equation 
are -
Step-by-step explanation:
= 
= 0
We can write 64 as 
+ = 0
using the identity ( 
)
we get,
= 
= 
....................(1)
solving the quadratic equation ,
=0
solutions of this quadratic equation can be obtained by
let use y for factors
<u />
..................(2)
from the equation 1 we have,
which gives solution 
and from equation 2 we got
so the real solutions for the equation are -
Step-by-step explanation:
if f(1)=-4, then adding 5 would give you 1, again would give you 6, again would give 11. Therefore, your first four terms are -4,1,6,11.
Cosine is
which applies to a right triangle. I hope that helps you.
The answer is B. 18
Explanation:
We know that a square has 4 right angles. A right angle is 90°.
5x° = 90°
5(18)° =90°
90°=90°
