Final answer:
When x = 10, the value of the expression 2.25x + 3 is 25.5 (in square units).
Step-by-step explanation:
To solve the addition problem 2.25x + 3 = ? when x = 10, we substitute the value of x into the expression and perform the calculation.
Step 1: Substitute x = 10 into the expression:
2.25(10) + 3
Step 2: Calculate the result:
2.25(10) + 3 = 22.5 + 3 = 25.5
Therefore, when x = 10, the value of the expression 2.25x + 3 is 25.5 (in square units).
