Answer:
Options (A) and (D)
Step-by-step explanation:
We can write the given division as,
Option (A)
When (2x² + 6x - 8) is divided (x + 5), the remainder is 12.
True.
Option (B)
When (2x² + 6x - 8) is divided (x - 5), the remainder is 12.
False.
Option (C)
When x = 5,
2x² + 6x - 8 = 12
2(5)² + 6(5) - 8 = 50 + 30 - 8
= 72
False.
Option (D)
When x = -5,
2(-5)² + 6(-5) - 8 = 50 - 30 - 8
= 12
True.
Option (E)
(x - 5) is a factor of 2x² + 6x - 8
If (x - 5) is a factor value of 2x² + 6x - 8 should be zero.
False.
Option (F)
(x + 5) is a factor of 2x² + 6x - 8
If (x + 5) is a factor then by substituting x = -5 in the expression value should be zero.
But the value is 12.
False.
Answer:
0.1905 = 19.05%
Step-by-step explanation:
We have a total of 106 containers of oxygen, from which:
20 have oxygen not ionized, 86 have oxygen ionized.
If the first one selected is ionized, now we have 20 not ionized and 85 ionized.
So the probability of the second one selected being not ionized is the number of not ionized (20) over the total number of containers (20 + 85):
P = 20 / (20 + 85) = 0.1905 = 19.05%

Answer:
no
Step-by-step explanation:
you cannot divide zero into two equal parts because there is nothing there to start. Since Pablo has no candy, he cannot divide it into two piles because there isn't anything to divide.
