Answer:
x² - 2xy + 3x + y² - 3y
Step-by-step explanation:
1: Multiply the second parentheses by each term from the first parentheses
X x(x - 1 y + 3) - y x (x - 1y + 3)
2: Distribute x through parentheses
Answer:
The correct answer is:

Step-by-step explanation:
By evaluating first, and then the mathematical calculation, we have:

Answer:
Frank
Step-by-step explanation:
First let's start by calculating the speed of each runner.
Let's use feet per second
Frank's speed is already given in feet per second: 14 feet/second
We are given that Jake runs 382 feet in 38 seconds. To bring this down to feet/second we need to divide both numbers by 38.
382/38=10.05 feet/second (about)
We are given that Will runs 1 mile in 394 seconds. 1 mile is equivalent to 5280 feet. Now we divide both numbers by 394 to bring it down to feet/second.
5280/394=13.401 feet/second (about)
We are given that Ron runs 555 feet in 1 minute. 1 minute is equivalent to 60 seconds. Now we divide both numbers by 60 to bring it down to feet/second.
555/60=9.25 feet/second
After comparing all the speeds, we can conclude that Frank runs the fastest
