Question

Fernando evaluated the expression below. What was Fernando’s error?

Answer 1

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

(should be +10 instead of -10)

Answer 2

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

Step-by-step explanation:

We have been given an image, which represents work of Fernando's evaluation of an expression. We are asked to find the error in Fernando's work.

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

Let us evaluate our given expression using order of operations (PEMDAS).

`(5(4))/(2)+(-2*-5)+9`

`(20)/(2)+10+9`

`10+10+9`

`29`

Since we know that product of two negative numbers is always positive, therefore, the product of negative 2 and negative 5 will be positive 10.

Therefore, Fernando incorrectly found the product of -2 and -5 and option C is the correct choice.
