By adding one more person, they each save $8
Total saving = 5 x 8 = 40
So $40 is what the 6th person has to pay.
Therefore the total rent is 6 x 40 = $240.
The answer is 4x that the answer
I think its b but not sure hope it helps though
X³ + 2x² - x - 2 < 0
x³ - x + 2x² - 2 < 0
x(x² - 1) - 2(x² - 1) < 0
(x - 2)(x² - 1) < 0
(x - 2)(x - 1)(x + 1) < 0
by chacking we get the solution
x ∈ (-∞,-1) ∪ (-1,1)
Answer: x³+y³=180
Step-by-step explain: let's remember the formula x³+y³=(x+y)(x²-xy+y²) and also x³+y³=(x+y)³-3xy(x+y) then
