Answer:

(-3 multiplied by 9 equals -27 and Huda has set 27)

Step-by-step explanation:

we have

[tex]-3(8-5)^{2}-(-7)[/tex]

[tex]-3(3)^{2}-(-7)[/tex]

[tex]-3(9)-(-7)[/tex]

[tex]-27-(-7)[/tex] -----> Huda's error (-3 multiplied by 9 equals -27 and Huda has set 27)

[tex]-27+7[/tex]

[tex]-20[/tex]

Answer:

Huda found the product of [tex]-3[/tex] and [tex]9[/tex] as positive [tex]27[/tex].

Step-by-step explanation:

We have been given an image, which shows Huda's work of evaluating an expression. We are asked to find Huda's error.

The given expression is: [tex]-3(8-5)^2-(-7)[/tex].

We will evaluate our given expression using order of operations PEMDAS.

[tex]-3(3)^2-(-7)[/tex]

[tex]-3(9)+7[/tex]

[tex]-27+7[/tex]

[tex]-20[/tex]

We can see from Huda's work that he found the product of negative 3 and 9 as positive 27, therefore, Huda made a mistake in 3rd step.
