Answer:
1) For : and , 2) For : and
Step-by-step explanation:
The polynomial is a second-order polynomial of the form . By direct comparison, we construct the following system of equations:
(1)
(2)
By (1) we know that there are a family of pairs such that the system of equations is satisfied. Let suppose that both and are integers. We assume two arbitrary integers for :
1)
2)
L=n-2, W=4+L=n+2
A=LW, since L=n-2 and W=n+2 we have:
A=(n-2)(n+2) so it could be this expression or the expansion
A=n^2-4
Answer:
the first box is,
the second box is 13.
-by-step explanation:
In a triangle, the hypotenuse is equal to the product of the length of a leg, x, and, and both legs are the same length.
Since the given leg length is 13, the other leg has a length of 13. The hypotenuse of the triangle equals the product of the leg length and, or.
Answer:
$1,080
Step-by-step explanation:
After the deductible is paid, $4,200-$300=$3,900 remain in fees. The policy pays 80% of this, which leaves 20% left, or 3,900*0.2=$780. Including the deductible of $300, the total cost is $780+$300=$1,080.
