Answer:
The correct option is C
Step-by-step explanation:
We have given the roots -6, 1 and 4.
Write down the roots:
x= -6 , x=1 , x=4
Rewrite the roots as an expression:
x+6=0
x-1=0
x-4=0
Now we have the following expressions:
=(x+6)(x-1)(x-4)
Now Multiply the terms:
=(x²-x+6x-6)(x-4)
=(x²+5x-6)(x-4)
=x(x²+5x-6) -4(x²+5x-6)
=x³+5x²-6x-4x²-20x+24
Solve the like terms:
=x³+x²-26x+24
Thus the correct option is C....
19 quantities of item A and 6 of item B were sold, respectively
<h3>How to determine the quantity sold</h3><h3>The missing information in the question are</h3>
- The cost of item A is $4 and
- The cost of item B is $2.
Using the information and the given parameters, we have the following system of equations:
A + B = 25
4A + 2B = 88
Multiply the first equation by 2
2A + 2B = 50
Subtract this equation from the second equation to eliminate B
2A = 38
Divide both sides by 2
A = 19
Substitute A = 19 in A + B = 25
19 + B = 25
Subtract 19 from both sides
B = 6
Hence, 19 quantities of item A and 6 of item B were sold, respectively

There are several important information's already given in the question. Based on those given information's the answer to the question can be easily deduced.
Number of stamps that Ira has in his stamp album = 128
Number of pages that the stamp album has = 8
Then
Number of stamps in each page of the stamp album = 128/8
= 16
So 16 stamps are there on each page of the stamp album. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar type of problems in future without requiring any additional help.
A and c are the correct answers
