Answer:
G
Step-by-step explanation:
Using the rule of exponents
=
Consider the left side
= , then
= n²
Since bases on both sides are equal, equate the exponents
x - y = 2 → G

Step-by-step explanation:
You need to used the following formula:
Where "V" is the speed, "d" is the distance and "t" is the time.
In this case you know that Kevin traveled at a constant speed on the highway from Hickory Hills to Chicago in 20 minutes (which is ) and the distance is 17 miles. Then, you can identify that:
Therefore, knowing these values, you can substitute them into the formula. Then, you get:
Answer:
The answer is (x + 3) (x - 7) = 0
Step-by-step explanation:
x² - 4x = 21
x² - 4x - 21 = 0
x² - 7x + 3x - 21 = 0
x(x - 7) + 3(x - 7) = 0
(x + 3) (x - 7) = 0
Thus, The answer is (x + 3) (x - 7) = 0
