F(x) = x^3 + 2x^2 - x - 2
<span>f(x) = x^2(x + 2) - (x + 2) </span>
<span>f(x) = (x^2 - 1)(x + 2) </span>
<span>f(x) = (x + 1)(x - 1)(x + 2) </span>
<span>Roots: -1, 1, -2 </span>
The unit price would be $30 per kg
Answer:
360
Step-by-step explanation:
270 = 75% of x
270 = 0.75 × x
0.75x = 270
x = 270/0.75
x = 360
Answer: 360
Answer:
X=0.2
Step-by-step explanation:
0.17x+1.2=1.234
0.17x=1.234-1.2
0.17x=0.034
17x=3.4
x=3.4/17
x=0.2
Answer: 24
Step-by-step explanation:
Okay, so if the part-time designer gets 200 dollars per week, we should subtract 200 by 800.
800 - 200 = 600.
Then we divide 600 by 25, and that will be the amount of completed designs we'll be able to have each week.
600 ÷ 25 = 24.
So in conclusion, you can pay the designer $200 per week and get 24 completed designs from him.
Hope this helps!
