I think 1/5 but i’m not sure. i don’t think i’m right
3x + x = 1044
4x = 1044 - divide both sides by four
x = 261
coffee table - $261
couch - $783
Answer:
1
Step-by-step explanation:
The function with the given zeros will factor as ...
f(x) = a(x +15)(x^2 +9) . . . . with leading coefficient 'a'
You have ...
f(2) = 221 = a(2+15)(2^2+9) = a(17)(13) = 221a
Then a = 221/221 = 1
The leading coefficient is 1.

<em>Additional comment</em>
As you know, a function with zero x=p has a factor of (x -p). The given zeros mean the function has factors (x -(-15)), (x -3i). and (x -(-3i)). The product of the last two factors is the difference of squares: (x^2 -(3i)^2) = (x^2 -(-9)) = (x^2 +9). This is how we arrived at the factorization shown above.
Answer:
Step-by-step explanation:
Since you're finding the angle, you use the inverse of sin, cos, and tan.
$3.78.
10% of 4.00 is .40 cents. Which makes the price with the discount 3.60. Since tax of 6% is per dollar, 3 times 6 is 18. Add it together and it becomes. 3.78$.
