The answer is not a whole number, so I'm not sure if I am 100% right.
The answer I got was 10.66666667 Pieces. Of course you wouldn't type that many 6's, just as many as it asks for. lol
Answer: The polynomial
= y² - 5y - 4.
Step-by-step explanation:
Let the polynomial = f(y)
Therefore
y² -5y + 1 - f(y) = 5
f(y) = y² - 5y + 1 - 5
f(y) = y² - 5y - 4
The polynomial = y² - 5y - 4.
Check:
y² - 5y + 1 - ( y² - 5y - 4)
Open the bracket with the minus
y² - 5y + 1 - y² + 5y + 4
y² - y² - 5y + 5y + 1 + 4
= 0 - 0 + 5
= 5.
Answer:
21square feet
Step-by-step explanation:
Count the whole squares first.
if each square is one square foot then 18 whole squares will be 18×1= 18 square feet
add halves (aproximate halves) together. (3 in total)
Therefore A= 18 +3
= 21 square feet
