Find the sum of the absolute values of the differences
Answer:
3
Step-by-step explanation:
Solve for x:
-6 + x = -3
Add 6 to both sides of the equal sign so -6 cancels out on the left side
+6 - 6 + x = -3 + 6
x = - 3 + 6
x = 3

Answer:
42
Step-by-step explanation:
Find the prime factorization of 126
126 = 2 × 3 × 3 × 7
Find the prime factorization of 420
420 = 2 × 2 × 3 × 5 × 7
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 3 × 7
GCF = 42
