V=120, l=8, h=1.5
W = V/hl
W=120/8(1.5) = 10
I hope this is in dollars. Remember to always put a label on a number. Who knows, maybe this person paid in bananas.
$45+$60+$7= $112.
I think it’s C
Explanation: the blue yarn is 7 and the red yarn is 10 if you combine both as 7 + 10= 17
Write the coeeficientes of the polynomial in order:
| 1 - 5 6 - 30
|
|
|
------------------------
After some trials you probe with 5
| 1 - 5 6 - 30
|
|
5 | 5 0 30
-----------------------------
1 0 6 0 <---- residue
Given that the residue is 0, 5 is a root.
The quotient is x^2 + 6 = 0, which does not have a real root.
Therefore, 5 is the only root. You can prove it by solving the polynomial x^2 + 6 = 0.
(2y +1)(4y + 1) is the factored form
