<h2>Given :-</h2>

The  difference between two positive numbers is 7 and the difference between these  cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,

<h3>To Find :-</h3>

  • A - B

<h2>Solution :-</h2>

So,

Let the number be n and m

A = n × m = nm

B = n² + m² = (n + m)²

Now

n³ - m³ = 805

(n - m) (n² + m² + nm) = 805

Since difference is 7

7 × n² + m² + nm = 805

n² + m² + nm = 805/7

n² + m² + nm = 115

(n² + n) + (m² + m) = 115

A + B = 115

Now

On squaring the first eq.

(n - m)² = (7)²

(n - m)² = 49

B - 2A = 49

Now

A + B - B + 2A = 115 - 49

A + 2A = 66

3A = 66

A = 66/3

A = 22

By using 2

B - 2(22) = 49

B - 44 = 49

B = 49 + 44

B = 93

A - B = 22 - 93 = -71

\bold{ A-B=-71  }

timofeeve [1]

Answer:

<h2>(7, 3)</h2>

Step-by-step explanation:

The formula of a midpoint:

\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)

We have (2, 3) and (12, 3).

Substitute:

x=\dfrac{2+12}{2}=\dfrac{14}{2}=7\\\\y=\dfrac{3+3}{2}=\dfrac{6}{2}=3
