Write an algebraic expression for two fifths of the square of a number

Answers

The algebraic expression for two-fifths of the square of a number will be (2/5)x².

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The square of the number means the number is multiplied by itself.

The algebraic expression for two-fifths of the square of a number will be

Let the number be x.

Then the square of the number will be

⇒ x²

And the two-fifth number is expressed as,

⇒ 2/5

The algebraic expression for two-fifths of the square of a number will be

⇒ (2/5)x²

Thus, the algebraic expression for two-fifths of the square of a number will be (2/5)x².

Solve linear system: x-y=6 and 2x=12+2y

Answers

2x = 2y + 12
 2          2
  x = y + 6

         x - y = 6
(y + 6) - y = 6
  y - y + 6 = 6
