Factoring Example: find the GCF of 20,50,120
Just find the factors of each number
The factors of 20 are 1,2,4,5,10,20
The factors of 50 are 1,2,5,10,25,50
The factors of 120 are 1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120
the common factors of 20,50,120 are 1,2,5,10 just the numbers common to all three.
the greatest common factor of 20,50,120 is 10
For the values of 36,144
is GCF = 36
Call the number x. Then we write
2x - 5 = 17
To solve, add 5 and divide by 2...
2x = 22
x = 11
Answer:
Indeed. The system of equations has a solution at point (0, -7).
Step-by-step explanation:
A system of linear equations is consistent only if exist a solution. Let equalize each expression to eliminate y and determine if a solution for x exist. That is:



Therefore, the system of linear equations has a solution at point (0, -7).
Usually, a square... But it can be a rectangle or a trapezoid.... Basically, all shapes with 4 sides, vertices, and labeled points of "A,B,C,D"
