<h3>
Answer: 43 km per hour</h3>
==================================================
Work Shown:
total distance = 43+40+46 = 129 km
total time = 1+1+1 = 3 hours
average speed = (total distance)/(total time)
average speed = (129 km)/(3 hrs)
average speed = (129/3) (km/hr)
average speed = 43 km per hour
You have the right idea that things need to get multiplied.
What should be done is that the entire fraction needs to get multipled by the lowest common denominator of both denominators.
Let's look at the complex numerator. Its denominators are 5 and x + 6. Nothing is common with these, so both pieces are needed.
The complex denominator has x - 3 as its denominator. With nothing in common between it and the complex numerator, that piece is needed.
So we multiply the entire complex fraction by (5)(x + 6)(x -3).
Numerator: 
= (x+6)(x-3) - (5)(5)(x-3)
= (x+6)(x-3) - 25(x-3)
= (x-3)(x + 6 - 25) <--- by group factoring the common x - 3
= (x -3)(x - 19)
Denominator:

Now we put the pieces together.
Our fraction simplies to (x - 3) (x - 19) / 125 (x + 6)

Answer:
A. Height is input, Weight is output
Step-by-step explanation:
We are given the statement,
"Weight is a function of height".
As we know,
<em>In a function of the form
, the input variable is 'x' and the output variable is 'y'.</em>
If we write the given statement in the form
, we get,

This means that the input variable is 'Height' and the output variable is 'Weight'.
Hence, option A is correct.
The answer for this question is D because you have 2 full squares and then one half of square so 2 1/2.
