4x +1

Step-by-step explanation:

f(x) = 3x - 1

g(x) = x + 2,

(f +g)(x)= 3x-1 + x+2

Combine like terms

          =4x +1

(f+g)(x)=4x+1

Step-by-step explanation:

This question asks us to find (f+g)(x), which is equal to adding f(x) and g(x).

f(x)+g(x)

We know that f(x) is 3x-1 and g(x) is x+2.

f(x)=3x-1

g(x)= x+2

(3x-1)+(x+2)

Combine like terms. Add all the terms with a variable, then all the terms without a variable.

(3x+x)+(-1+2)

(4x)+(-1+2)

(4x)+(1)

4x+1

(f+g)(x)=4x+1

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
