Answer:
D
Step-by-step explanation:
Roots into factors:
x = -4 ----> (x + 4)
x = i -----> (x - i)
x = 5 -----> (x - 5)
(x + i)(x - 4)(x + 5)
(x - i)(x² - 4x + 5x - 20)
(x - i)(x² + x - 20)
x³ + x² - 20x - (ix² + ix - 20i)
x³ + (1 - i)x² - (20 + i)x + 20i
2.5= 2 1/2
just do 10/20= .5 so 7.5
8.2= 8 2/10 which simplifies to 8 1/5
2.88=2 <span>22/<span>25
</span></span>
3/6= 7.5
3 1/4= 3.25
i couldn't see the other ones except for also 12
2.1= 2 1/10
Answer:
...
Step-by-step explanation:
Number of 6th grade student students:
Sharon: 156x(1/2) = 78
Deacan: 156x(1/4) = 39
Banyon: 156x(1/6) = 26
New: 156x(1/12) = 13
------
TOTAL 156
Sharon = 78 and Deacan = 39 then 39 more student than Sheraton thanDecan
