Answer:

-a^2 + 2 ab + b^2

Step-by-step explanation:

To solve this, you need to distribute the letters into the parenthesis.

Then, you sum equal things, and you get the result.

b(a+b)-a(a-b)=\\ba + b^{2} -a^{2}  + ab=\\ b^{2} + 2ab -a^{2}

So, the rigth answer is number three: -a^2 + 2 ab + b^2

Find the distance between the points (1, 0) and (0, 2). √3 √5 1
GalinKa [24]

For this case we have that by definition, the distance between two points is given by:

d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}

We have the following points:

(x_ {1}, y_ {1}): (1,0)\\(x_ {2}, y_ {2}): (0,2)

Substituting we have:

d = \sqrt {(0-1) ^ 2 + (2-0) ^ 2}\\d = \sqrt {(- 1) ^ 2 + (2) ^ 2}\\d = \sqrt {1 + 4}\\d = \sqrt {5}

Thus, the distance between the points is\sqrt {5}

Answer:

d = \sqrt {5}

A patient's total surgery charges are $1,278. The patient must pay the annual deductible of $1,000, and the policy states a 80-2
musickatia [10]

Answer:

The patient owe $1255.6 .

Step-by-step explanation:

As given

A patient's total surgery charges are $1,278.

The patient must pay the annual deductible of $1,000.

The policy states a 80-20 coinsurance.  (i.e 20% of the surgery amount is given by the patient .)

20% is written in the decimal form .

= \frac{20}{100}

= 0.20

20% of patients surgery cost  =  0.20 ×  $1278

                                                 = $ 255.6

Patients owe = Deductible cost + 20% of patients surgery cost

                      = $1000 + $255.6

                      = $ 1255.6

Therefore the patient owe $1255.6 .
