The correct answer is x = 3
4 +5 = 9 and 12 + 3 =15 and there is more than this
hope I helped
I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A

: It looks like this in the calculator

× cos A=

(0.6489)
(

and cos cancels out)
A=

(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)
Answer:
It diverges.
Step-by-step explanation:
We are given the inetegral: 

So it is divergent.
Answer:
12x+24
