Simple....
you have:
5x+2=4x-9
5x+2=4x-9
-4x -4x
x+2=-9
x+2=-9
-2 -2
x=-11
Thus, your answer.

Prime= 37, 71 Composite= 65, 82
Step-by-step explanation:
Prime numbers can only be divided by 1 and itself and composite numbers can be divided by more.
Since line c and d are parallel, line a can act as a transversal. Thus, x=124 degrees because of the alternate exterior angle relationship that can be seen.
Answer:

Step-by-step explanation:
Both numbers are integers (not fractions)
if you write an integer in scientific notation:
1) inset a comma between first and second digit (3.70000000)
2) calculate all digits on the right side of insetting comma (there are 8 digits after a comma: 7,0,0,0,0,0,0,0)

4) according this tips, you have 
5) for a better notation, you may remove ending zeros
