First, factor the expression on the top. What two numbers add to get 8 and multiply to 15? 5 and 3! so the top expression factors to (x+3)(x+5). You can cancel the x+3 from the denominator and end up with x+5. Make sense?
Step-by-step explanation:
<u>Substitute the given value of x into the expression;</u>

Answer:
The original distance between Dallas and Houston is 240 miles.
Step-by-step explanation:
The scale on a map is 1 cm = 50 miles.
That means, 1 cm length in the drawing is equivalent to 50 miles original distance.
We have to find the actual distance between Dallas and Houston, which are 4.8 cm distant on the map.
So, 4.8 cm length in the drawing will be equivalent to (50 × 4.8) = 240 miles.
Therefore, the original distance between Dallas and Houston is 240 miles. (Answer)
5,382,600 is going to be your answer
