What is the value of the expression when n = 3?
-2n(5 + n - 8 - 3n)
○ 12
○ 24
○ 42
○ 54
-2n(5 + n - 8 - 3n)
○ 12
○ 24
○ 42
○ 54
To find the value of the expression when n = 3, substitute n with 3 in the expression:
-2(3)(5 + 3 - 8 - 3(3))
Simplify inside the parentheses:
-2(3)(5 + 3 - 8 - 9)
-2(3)(5 + 3 - 17)
-2(3)(-9)
Now, calculate the expression:
-2(3)(-9) = -2 * 3 * -9 = 54
The value of the expression is 54.
