Step-by-step explanation:
987 → 789
987 - 789 = 198
876 → 678
876 - 678 = 198
765 → 567
765 - 567 = 198
654 → 456
654 - 456 = 198
543 → 345
543 - 345 = 198
432 → 234
432 - 234 = 198
321 → 123
321 - 123 = 198
Generally it is always like that:
3 ≤ x ≤ 9
100x + 10(x-1) + (x - 2) → 100(x - 2) + 10(x - 1) + x
(100x + 10(x - 1) + (x - 2)) - (100(x-2) + 10(x-1) + x)
= 100x + 10(x - 1) + (x - 2) - 100(x - 2) - 10(x - 1) - x <em>cancel 10(x - 1)</em>
= 100x + x - 2 - 100x + 200 - x <em>cancel 100x and x</em>
= 100 - 2
= 198
The answer to this question is metaphor
F(x) = 5x³ + 24x² - 75x + 14
Set each given factor equal to 0 and obtain 4 values of x:
A) x = -1/2
B) x = 1/2
C) x = -2
D) x = 2
Now, use the hit and trial method to find the answer. We are looking for a value of x which will put f(x) = 0
5(-1/2)³ + 24(-1/2)² - 75(-1/2) + 14
=/= 0
5(1/2)³ + 24(1/2)² - 75(1/2) + 14
=/= 0
5(-2)³ + 24(-2)² - 75(-2) + 14
= /= 0
5(2)³ + 24(2)² - 75(2) + 14
= 0
Thus, the answer is D
The answer is b. N - 8 = 22
