I think it's either 18 or 24.. I've had this question before but I'm not positive which answer I put and if it was correct, sorry I couldnt help much :(
The triangle BCD is an acute triangle
M + R + G = 119
G = 3M
M = R + 6 —> R = M - 6
1st equation: M + (M-6) + (3M) = 119
5M -6 = 119
5M = 125
M = 25
G = 3(25) = 75
R = (25) -6 = 19

2nd option
Step-by-step explanation:
Simplify first what is in the parenthesis before distributing the exponent outside would help.
Remember that negative exponents simply means that their on the wrong side of the fraction. So if you find a variable with a negative exponent as a numerator, you bring them down and when it is found as a denominator, you bring them up.
Also when you distribute your exponents, you always multiply it to each exponent inside the parenthesis.
