By that information only i would think the answer is 45k+20, sorry if that’s not right
Answer:
its G
Step-by-step explanation:
First you need to know that square means multiplicatin by itself to itself so square of 20 means 20×20=400
Answer:
(f-g) (3x)=27x^3+12+2
Step-by-step explanation:
First lets write the following:
(f-g) (3x)= f(3x)-g(3x)
Now we need to find equivalent expression for f(3x) and for g(3x), we will obtaine them by evaluating 3x instead of x in every 'x' appearance.
Wi have>
g(3x)= -27x^3+4
f(x)=12x-2
Now, lets perfomr the desired operation.
f(3x)-g(3x)=27x^3+12+2
