Answer:
see explanation
Step-by-step explanation:
Using the identity
(a + b + c)³ = a³ + b³ + c³ + 3 [ (a + b + c)(ab + bc + ac) - abc ], then
5³ = a³ + b³ + c³ + 3(5 × 10) - 3abc, that is
125 = a³ + b³ + c³ + 150 - 3abc, hence
a³ + b³ + c³ - 3abc = 125 - 150 = - 25
$0.59 x 8 = 4.72
4.72 + 5.87 = 10.59

The answer for your question is D
Answer:
The tax Jenna and Richie pay on the gifts is <u>$3.85</u>.
Step-by-step explanation:

Cost of necklace = $35.65.
State tax charges sale tax = 8%.
Now, to find the sales tax paid on the gifts.
So, adding the price of the gifts:
Thus, the total amount of the gifts = $48.10.
Now, getting the sales tax the state charges:
<em><u>The tax nearest to cent = $3.85</u></em>
Therefore, the tax Jenna and Richie pay on the gifts is $3.85.
Answer:
x^3-4x^2+25x-100
Step-by-step explanation:
We have 2 roots -5i and 4. Using the conjugate root theorem for the root -5i, we know that 5i should be another root
Combining the roots into a polynomial gives us:
(x+5i)(x-5i)(x-4)
Expand:
(x^2 + 25)(x-4)
x^3-4x^2+25x-100
