Answer:

9t^2+(t+2)^2

Step-by-Step:

t is 9 X t, or the product of 9 and t. ^2 is squared while + is increased t+2 is the sum of t and t. the ^2 after the parenthesis is indicating the "square of t and 2"

The mathematical expression is 9t² +  (t + 2)² if the product of 9 and t squared, is increased by the sum of the square of t and 2.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The product of 9 and t squared, increased by the sum of the square of t and 2

Here t is the number.

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division.

The product of 9 and t squared is:

= 9t²

The sum of the square of t and 2

= (t + 2)²

The sum of the expression 9t² and (t + 2)²

= 9t² +  (t + 2)²

Thus, the mathematical expression is 9t² +  (t + 2)² if the product of 9 and t squared, is increased by the sum of the square of t and 2.
