since angle bisector divides the opposite side in same ratio of other two sides
18/12=12/x
x=12×12/18
x=8

Step-by-step explanation:
GCF of 72 and 18 by Prime Factorization
As visible, 72 and 18 have common prime factors. Hence, the GCF of 72 and 18 is 2 × 3 × 3 = 18.
Answer:
The system has no solutions.
Step-by-step explanation:
If you stare at it for the bit you can tell the system is impossible. Let's see why:
First of all, rewrite the second equation by bringing all unknowns on the LHS:
.
Then take twice the first equation, doubling every coefficient:
See how the LHS is the same? The system is asking you to find a quantity (4x+6y) which is at the same time equal to four AND five - emphasis on that "and" - which is obviously impossible, because it implies that 4=5. So the point - which you didn't provide - is not a solution. Nor is any other point.
A.
B, C, and D would be represented by 6/5
