Answer:
n=−7
Step-by-step explanation:
5−2n=19
n=-7
- If x = 5 is a zero of the given polynomial, then,
- (x - 5) is a factor of the polynomial. [Since, x = 5 or, x - 5 = 0]
- Now, divide the polynomial with (x - 5) using long division method. (See the picture)
- We get (x^2 - x - 6) as the quotient.
- Now, factorise the above polynomial:
- (x^2 - x - 6)
- = (x^2 - 3x + 2x - 6)
- = x(x - 3) + 2(x - 3)
- = (x - 3)(x + 2)
- Therefore, x^3 − 6x^2 − x + 30 = (x − 5)(x − 3)(x + 2)

Step-by-step explanation:
The difference in the length of the polar bear will be:
= 2 7/9 - 1 5/6
The lowest common multiple of 9 and 6 is 18.
= 2 7/9 - 1 5/6
= 2 14/18 - 1 15/18
= 17/18
She is incorrect as she subtracted the denominator from the numerators and didn't find their lowest common multiple. She got the answer this way:
= 2 7/9 - 1 5/6
= (2 - 1) (7-5)/(9-6)
= 1 2/3
