Answer 2

Answer:

n = 3

Step-by-step explanation:

-1(n2 + 3) if n = -3.

from the question

-1(n2 + 3)

we are then asked to find n if its equals to -3

solution

-1(n2 + 3) .................. we are going to open the bracket with-1 according to BODMAS rule

we have,

-n²-3

when the value of n = -3

we have,

= (-3)² - 3

= 9 - 3

= 3

therefore  when n = -3 in the expression -1(n2 + 3)  the value of n = 3

to check if your answer is correct you will put the value of n which is 3 into the -1(n2 + 3)  then you will see that the right handside = lefthandside

which is

3=3...........proved.
