Answer:
Question 4: (C)
Question 5: (B)
Step-by-step explanation:
1. so the scale factor between the two shapes 2/3 because 6 is 2/3 of 9
and 9 is 3/2 of 6. Therefore y would equal 6 also, x would equal 8, because 8 is 2/3 of 12, and z would equal 5 1/4.
Sorry but I don't know how to work out the second one.
Answer:
and 
Step-by-step explanation:
Given:
The rational equation to solve is given as:

We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

Now, for
, the rational equation is equal to 0. So,
is a solution.
Also,
is also a solution as the equation's denominator is defined at that point.
So, no extraneous solution.
