just add them up. ans:14 1/4 pounds
Answer:
x^3 -9x^2 +14x +24
Step-by-step explanation:
(x-4)(x^2 - 5x - 6)
Multiply the x by everything in the second term
x * (x^2 - 5x - 6)
x^3 -5x^2 -6x
Multiply the -4 by everything in the second term
-4 * (x^2 - 5x - 6)
-4x^2 +20x +24
Add everything together
I like to line them up vertically
x^3 -5x^2 -6x
-4x^2 +20x +24
-------------------------------
x^3 -9x^2 +14x +24

Answer: (x + 7)(x - 7)
Explanation: If a variable is taken to an even power, that variable is a perfect square. In this case, x² would therefore be a perfect square.
Since 49 is also a perfect square, what we have here is the difference of two squares. That can be factored as the product of two binomials one with a plus in the middle and one with a minus in the middle.
In the first position will be the factors of x² that are the same.
So we have <em>x</em> and <em>x</em>.
In the second position we will have the
factors of 49 that are the same, 7 and 7.
(x + 7)(x - 7) is your answer which is a factored version of x² - 49.
The expression will be 3 + n
