e - [(r/r) + 6]
(e-r)/(r+6) = (6 - -9)/(-9+6) = 15/-3 = .....
It seems like there might be a mistake in your calculation. Let's go through it step by step.
The expression you provided is (e - r) / (r + 6), where e = 6 and r = -9.
Step 1: Substitute the given values for e and r:
(6 - (-9)) / (-9 + 6)
Simplify the expression within the parentheses:
(6 + 9) / (-3)
Step 2: Perform addition:
15 / (-3)
The sum is 15 divided by -3.
Now, since the numerator and denominator have different signs, the resulting fraction will be negative:
-15 / 3
Finally, simplify the fraction:
-5
So, the correct answer would be -5, not 1.
