Since ur using r as a variable the answer is r = 7.
Since you have to distribute both numbers, you'll end up with x^2-3x+4x-12 then simplify and it is x^2+x-12
F(2)+g(4)
evaluate them seperately
f(2)=2+2=4
g(4)=10(4)-4
g(4)=40-4
g(4)=36
f(2)+g(4)=4+36=40
Answer:
The probability of choosing a yellow marble is 5/11
Step-by-step explanation:
