write your answer as an integer or a decimal. do not round

Explanation:

Step1: Calculate inside the parentheses

First, add 2.9 and 6.4: $2.9 + 6.4 = 9.3$. Then subtract 9 from that result: $9.3 - 9 = 0.3$.

Step2: Square the result

Now, square the number we got from the parentheses: $(0.3)^2 = 0.09$.
