Answer 1

Fernando incorrectly found the product of -2 and -5.

Step-by-step explanation:

Given the expression;

`(5(9-5))/(2)+(-2)(-5)+(3)^2`

Let us simplify the expression;

`\begin{gathered} (5(9-5))/(2)+(-2)(-5)+(3)^2 \\ (5(4))/(2)+10+9^{} \\ (20)/(2)+10+9 \\ 10+10+9 \\ 29 \end{gathered}`

So, the solution is 29.

Fernando's error was with the (-2)(-5), minus times minus is plus not minus.

Therefore;

Fernando incorrectly found the product of -2 and -5.
