Answer 2

The value of the expression at y = 2.5 is 6.25.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

y²

Substitute y = 2.5

= y²

= 2.5²

= 2.5 x 2.5

= 6.25

Thus,

The value is 6.25.
