The answer for this question that needs an answer is n = 5
because 18(n-1) = 9(n+7) implies that 18n - 18 = 9n + 63 which implies that n =5 for the equation to hold true.
Sum of 2 perfect cubes
a³+b³=(a+b)(x²-xy+y²)
so
x³+4³=(x+4)(x²-4x+16)
set each to zero
x+4=0
x=-4
the other one can't be solveed using conventional means
use quadratic formula
for
ax^2+bx+c=0
x=
![\frac{-b+/- \sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-b%2B%2F-%20%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D%20)
for x²-4x+16=0
x=
![\frac{-(-4)+/- \sqrt{(-4)^2-4(1)(16)} }{2(1)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-%28-4%29%2B%2F-%20%5Csqrt%7B%28-4%29%5E2-4%281%29%2816%29%7D%20%7D%7B2%281%29%7D%20)
x=
![\frac{4+/- \sqrt{16-64} }{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%2B%2F-%20%5Csqrt%7B16-64%7D%20%7D%7B2%7D%20)
x=

x=
![\frac{4+/- (\sqrt{-1})(\sqrt{48}) }{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%2B%2F-%20%28%5Csqrt%7B-1%7D%29%28%5Csqrt%7B48%7D%29%20%7D%7B2%7D%20)
x=
![\frac{4+/- (i)(4\sqrt{3}) }{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%2B%2F-%20%28i%29%284%5Csqrt%7B3%7D%29%20%7D%7B2%7D%20)
x=
![2+/- 2i\sqrt{3}](https://tex.z-dn.net/?f=%202%2B%2F-%202i%5Csqrt%7B3%7D%20%20)
the roots are
x=-4 and 2+2i√3 and 2-2i√3
Answer:
Step-by-step explanation:
She makes $325 a week, so go to the 8th row, for weekly income of $300 to $400. She claims 2 exemptions, so go to the third column labeled 2. The value is 2. That means the $2 is withheld from her paycheck on top of the 6.25% for FICA. The total is therefore:
$2 + (0.0625) ($325)
$22.3125
Rounded to the nearest cent, that's $22.31.
