Hello from MrBillDoesMath!
Answer:
x^3 - 6 x^2 - x + 6
Discussion:
The polynomial is
(x-1) (x - (-1)) (x-6) =
(x-1)(x+1)(x-6) = => as (x-1)(x+1) = x^2 - 1
(x^2-1)(x-6) =
x^2(x) - 6 x^2 - 1x + 6 =
x^3 - 6 x^2 - x + 6
Thank you,
MrB
Correct amswer is 4 whole pieces
To silpify the expression we proceed as follows:
(x+7)/(x^2+4x-21)
Factorizing the given the denominator:
x^2+4x-21
x^2-3x+7x-21
=x(x-3)+7(x-3)
=(x-3)(x+7)
thus plugging back in our expression we have:
(x+7)/[(x-3)(x+7)]
simplifying this we obtain:
1/(x+3)
Answer: 1/(x+3)
Answer:
$11.5
Step-by-step explanation:
Subtract 30 from 64.50 to get rid of the cost of shirts. (3 shirts costing 10 dollars) to get 34.50. DIvide 34.50 by 3 for the number of shorts. Your final answer is 11.5
