Answer:
(a-1) *(a^2 +a-1) (a+2)
Step-by-step explanation:
a^4+2a^3-a-2
Lets factor by grouping
a^4-a + 2a^3-2
Factor out an a from the first group and a 2 from the second group
a(a^3 -1) +2(a^3-1)
Factor out (a^3-1)
(a^3-1)(a+2)
We need to recognize that a^3-1 is the difference of cubes
(x^3-y^3) = (x-y) (x^2+xy+y^2)
Let x=a and y=1
(a-1) *(a^2 +a-1) (a+2)
Answer:
x=-2
Step-by-step explanation:
ok so you have to subtract -x from -9x (you would make x a one) which would be -8,and then you subtract 1 from 17,which would be 16 then you divide that from -8,so the answer would be x=-2
Answer:
= 15%21%2F%2812%21%2A3%21%29 = %2812%2A11%2A10%29%2F%281%2A2%2A3%29 = 2*11*10 = 220.
Step-by-step explanation:
$14 is 9.5238% of $147
So, calculating 9.5238% of $84, we get $7.99, which would lead me to say.
The answer to your question is C> $8.00
