55mph.
you can solve it using the equation distance=speed x time
your total distance is 714, and you have 2 trains, one traveling some speed, x, and one traveling x+8, both traveling for 7 hours.
your equation would look like this
and you can then solve for x, which would be 47. this is the speed of the slower train, but 47+8=55 with give you the speed of the faster train.
Given expression:
2x(x + 7)-(3x +1);
To distribute implies to spread a process equally in an expression. Often times, the distributive property is used for expressions inside parentheses;
2x(x + 7)-(3x +1)
Distribute 2x over the first parentheses;
the negative sign distributes over the second part
= (2x² + 14x) - 3x -1
= 2x² + 14x -3x -1
Add like terms;
= 2x² + 11x -1
This expression 2x² + 11x -1 is equal to the given one
The analyst believes the value of the stock at the end of three weeks will be $134.

What are stocks?</h3>
- Stock (also known as capital stock) in finance refers to the shares of ownership in a corporation or company.
- A single share of stock represents fractional ownership of the corporation based on the total number of shares.
- This typically entitles the shareholder (stockholder) to that fraction of the company's earnings, proceeds from asset liquidation (after discharge of all senior claims such as secured and unsecured debt), or voting power, which are often divided in proportion to the amount of money invested by each stockholder.
To find the value of the stock:
- Because the stock price drops by 28% every week, it will be:
- 100 - 28 = 72% every week.
- So, r = 0.72.
- Then, the equation V = 360(r)∧t will be V = 360(0.72)∧t .
- After 3 weeks, V = 360(0.72)³ = 134.47 = 134
Therefore, the analyst believes the value of the stock at the end of three weeks will be $134.
