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.
ok did you get what I solved I hope it's fine by you, if you have a problem with the way I solved it still ask questions ok
Answer:
Step-by-step explanation:
total price was reduced by $ 7
let x = the total price........ x - 7
he bought 10.....and it cost him $ 130
10(x - 7) = 130
10x - 70 = 130
10x = 130 + 70
10x = 200
x = 200/10
x = 20 <====== original price
Answer:
C. Surveys
Step-by-step explanation:
A primary source of information is the gathering of data that hasn't already been collected.
One of the best ways is to use a market research survey.
A, B, and D are wrong. They are all secondary sources — they provide information that someone else has generated.
