Answer:
12
Step-by-step explanation:
b-4x
Plug in 4 as b and -2 as x
= (4)-4(-2)
Multiply 4 and 2
= 4-(-8)
Two negatives make a positive
= 4+8
= 12
I hope this helps!
The answer is 12+3r because 4 times 3=12 then the 3r which you cannot add because they are no others variables that are r
That is a rational number since you can write it as a ratio (=fraction).
