Answer:
(2n + 5) / M
n = -4
M = -3
(2(-4) + 5) / (-3)
Simplify the numerator:
(-8 + 5) / (-3)
Now, perform the subtraction in the numerator:
(-3) / (-3)
Finally, divide the numerator by the denominator:
(-3) / (-3) = 1
So, when n = -4 and M = -3, the value of the expression (2n + 5) / M is equal to 1.
