Answer:
either 81 or 162
Step-by-step explanation:
I got 81 by 27×12
162=27×12×2
Answer:
- 2 groups of 6
- 6 groups of 2
- 4 groups of 3
- 3 groups of 4
- 1 group of 12
- 12 groips of 1
Step-by-step explanation:
To figure out the possible groups find the factors of 12; in other words what two numbers would multiply to 12. These are: 1, 2, 3, 4, 6, and 12
- 1 × 12 = 12
- 2 × 6 = 12
- 3 × 4 = 12
- 4 × 3 = 12
- 6 × 2 = 12
- 12 × 1 = 12
So, your possible groupings are;
- 2 groups of 6
- 6 groups of 2
- 4 groups of 3
- 3 groups of 4
- 1 group of 12
- 12 groips of 1
First step: multiply the 5(x3) and it will give you x15 or most commonly written as 15x. you should now have 15x-(-20).
Second step: since you cannot subtract -20 from 15x because it has a variable, the final answer is just 15x-(-20), or 15x+20.
- 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)
