It is called a difference of squares because there are two things squared being subtracted. You can recognize it when there are two terms, subtraction between the two of them, and you know the square root of both

Answer:
3yz² - 3z² - 5y + 7
Step-by-step explanation:
Sum of two polynomials = –yz² - 3z² – 4y + 4
One of the polynomial = y - 4yz²- 3
Find the other polynomial
The other polynomial = sum of the polynomials - one of the polynomial
= –yz² - 3z² – 4y + 4 - (y - 4yz² - 3)
= –yz² - 3z² – 4y + 4 - y + 4yz² + 3
= -yz² + 4yz² - 3z² - 4y - y + 4 + 3
= 3yz² - 3z² - 5y + 7
A. 0 -2yz?
B. – 4y + 7 01 - 2yz
C. – 3y + 1 0 -5yz² + 3z² – 3y + 1 D. 3yz² - 3z² – 5y + 7
The speed is the distance covered by an object at a particular time. The distance that is covered by the vehicle is 3,391 miles.
<h3>What is speed?</h3>
The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Speed = Distance / Time
Given that the journey took 9 days. Therefore, the time in hours will be equal to,
Time = 24 hours/day × Number of days
= 24× 9
= 216 hours
Also, given that the speed of the vehicle is 15.7 miles per hour, the number of hours for which it travels is 216 hours.
Distance = Speed × Time
= 15.7 miles/hour × 216 hours
= 3,391.2 miles
Hence, the distance that is covered by the vehicle is 3,391 miles.

Answer:
B. 1/9
Step-by-step explanation:
The positive square root of "x^2 - 4x + 4" is "x - 2". That value is already given to you, 1/3. Just square 1/3 to get 1/9.
