Show that (a-b)/(√a-√b)=√a+√b for all values of a and b such that a> 0 and b> 0 and a≠b.
goldfiish [28.3K]

Answer:

Step-by-step explanation:

\frac{a-b}{\sqrt{a} -\sqrt{b}} =\sqrt{a} +\sqrt{b}\\or ~a-b=(\sqrt{a} +\sqrt{b})(\sqrt{a}  -\sqrt{b} )=(\sqrt{a} )^2-(\sqrt{b} )^2 =a-b

Write an equation as part of solving the problem. The purchase price of a large 4K LED TV, including finance charges, was $1480.
Leto [7]

Answer:

$57.50

Step-by-step explanation:

1480 = 100 + 24x

1480 - 100 = 24x

1380 = 24x

x = 1380/24

x = $57.50, where x represents the monthly payments.

The average of a list of 4 numbers is 90.0. A new list of 4 numbers has the same first 3 numbers as the original list, but the f
Thepotemich [5.8K]

Answer:

the average of this new list of numbers is 94

Step-by-step explanation:

Hello!

To answer this question we will assign a letter to each number for the first list and the second list of numbers, remembering that the last number of the first list is 80 and the last number of the second list is 96

for the first list

\frac{a+b+c+80}{4} =90

for the new list

\frac{a+b+c+96}{4} =X

To solve this problem consider the following

1.X is the average value of the second list

2. We will assign a Y value to the sum of the numbers a, b, c.

a + b + c = Y to create two new equations

for the first list

\frac{y+80}{4} =90

solving  for Y

Y=(90)(4)-80=280

Y=280=a+b+c

for the second list

\frac{y+96}{4} =X\\

\frac{280+96}{4} =X\\x=94

the average of this new list of numbers is 94

Also, good problem solving activities provide an entry point that allows all students to be working on the same problem.

In this case, the open-ended nature of problem solving allows high achieving students to extend the ideas involved to challenge their greater knowledge and understanding and problem solving develops mathematical power.
