Answer:
6u^3
Step-by-step explanation:
x^2 - 4
------------------------------
x + 7 | x^3 + 7x^2 - 4x - 28
x^3 + 7x^2
------------------
0 - 4x - 28
-4x - 28
-------------
0
Now we know that
x^3 + 7x^2 - 4x - 28 = (x^2 - 4)(x + 7)
x^2 - 4 can be factored since it is the difference of two squares.
x^2 - 4 = (x + 2)(x - 2)
The complete factoring is:
x^3 + 7x^2 - 4x - 28 = (x +2)(x - 2)(x + 7)
Whoever sees this have a great day ❤️
Mikel carried the ball 4 1/2 yards. Let’s convert this: 9/2 yards (4*2+1), and if Fred carried it twice as far, that means he carried it 2 times 9/2. We know that 9/2 (or 4.5) * 2 is 9, so he carried it 9 yards.
