Answer:
B is true
Step-by-step explanation:
given f(x) = 2x² - x - 1 and g(x) = x - 1
A
If x = - 1 is a root then f(- 1) = 0
f(- 1) = 2(- 1)² - (- 1) - 1 = 2 + 1 - 1 = 2 ≠ 0 ← False
B
If (x - 1) is a factor then x = 1 is a root and f(1) = 0
f(1) = 2(1)² - 1 - 1 = 2 - 1 - 1 = 0
⇒ g(x) = x - 1 is a factor of f(x) ← True
C
If x = 2 is a root then f(2) = 0
f(2) = 2(2)² - 2 - 1 = 8 - 3 = 5 ≠ 0 ← False
D
= 
Cancel the factor (x - 1) on the numerator/ denominator, leaving
= 2x + 1 with remainder 0 ≠ 2 ← False
Answer:
i think 5 so i say pick 5 because 19no 12no10 no so it 5
Answer
Find out the how much twine will he needs to pack 29 cartons today .
To proof
As given
uhammad, a shipping and receiving clerk, uses 1 yard, 2 feet, 4 inches of twine to wrap each carton he packs.
As given in the question
Convert the answer to larger units .
As between yard is the largest unit between yard, feet and inches.
and
Convert 2 feet into yard
Convert 4 inches into yard
twine to wrap each carton packs
L.C.M of (3 , 36) = 36
than the equation becomes
=1.77777778 yard
Now twine to wrap pack 29 cartons = 29× 1.77777778
= 51.5555556 yard
Now twine to wrap pack 29 cartons is 51.55 yard ( approx)
Hence proved
Answer:
36 I think, also to fintd the are of an object you count how many shapes its in the object:).
