Answer:
x=9
<A=23
<B= 69
Step-by-step explanation:
1. 2x+5+3(2x+5)=92 2. 2x+5+6x+15=92 3. 8x+20=92 4. 8x=72 5. x=9
<A= 2(9)+5=18+5=23
<B= 3(2(9)+5)=3(23)=69
Quadrant I : cot(x) > 0 → -cot(x) < 0
Quadrant II : cot(x) < 0 → -cot(x) > 0
Quadrant III : cot(x) > 0 → -cot(x) < 0
Quadrant IV : cot(x) < 0 → -cot(x) > 0

Answer: a)
We know that one answer is only true, so we did not check the correctness of the cotangent value, only to the number sign
The ratio of x and 2=x:2
not greater than is <
So I'd say the answer would be x:2<14
Answer:
the correct answer is C the system of equations has no solution.
