Answer 2

Answer:

Required answer is 100.

Step-by-step explanation:

Given,

Divide 40 by half the add 20

First 40 divided by half

$= 40 \div \frac{1}{2} \\ = \frac{40}{ \frac{1}{2} } \\ = \frac{40 \times 2}{1} \\ = 80$

Now add 20 with it

So,

$(80 + 20) = 100$

Required answer is 100.

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
