Answer: 
Step-by-step explanation:
Factor theorem : If x=a is a zero of a polynomial p(x) then (x-a) is a factor of p(x).
Given: Zeroes of polynomial : -4,0, 1, and 4.
Then Factors = 
[By factor theorem ]
Multiplying these factors to get polynomial in standard form.
Hence, B is the correct option.
Answer:
You can use a hint
Step-by-step explanation:
Press the Use a hint button, the first time it won't count, only then the second one won't count.
Y= 12 - x
27 + 3( 12 - x ) = 2x
Answer:
k = 0.381cm/gallon
Step-by-step explanation:
Let the amount a tree grows in one month be x
Let amount of water it is given be y
If the amount a tree grows in one month is directly proportional to the amount of water it is given, then;
x ∝ y
x = ky
k is the constant of proportionality
k = x/y
Given
x = 8cm
y = 21 gallons
k = 8/21
k = 0.381cm/gallon
Answer:
20 books
Step-by-step explanation:
given that the shelf can hold 25 1/2 lbs (i.e 25.5 lbs), and that each book weighs 1 1/4 ln (i.e 1.25 lbs)
number of books which the shelf can hold
= weight that the shelf can hold ÷ weight of each book
= 25.5 ÷ 1.25
= 20.4 books
because having 0.4 of a book (i.e part of a book) would not be very feasable, we have to round the number of books down to the nearest whole number)
20.4 books rounded down to nearest whole number = 20 books (answer)
