The factored expression is: 3(5n-6)
The GCF between 15 and 18 is 3. So you would divide both numbers by 3. That would leave you with 5 taking the place of 15 and 6 taking the place of 18. Then you would fill in the blanks. Three multiplied by the expression 5n-6 would give you your original expression of 15n-18.
Answer:
see below
Step-by-step explanation:
There are no variables x or y or z in the given expression, so all but the answer shown below are irrelevant.
The denominator factors as ...
ab³(a² +ab +b²)
so the restrictions are that these factors cannot be zero. The cases listed in the answer choice shown are the cases that are <em>not allowed</em>.
You can use the coordinates to find the slope of each line. If you can show the two slopes are equal, then the lines are parallel.
Side note: If the lines are vertical, and never cross, then they will be parallel despite having an undefined slope. This is one of the exceptions to the rule.
