Answer:
is it A?
Step-by-step explanation:
I think it's A because no one has answered!
When you are doing derivatives, you don't want to do it right away because there is still ( ) we need to remove that first get,
g(x)=3x^4-6x
Now we can do the derivatives!
g(x)=12*x^3 - 6
I hope this helps!
Since they are congruent, cpctc,
just set the congruent parts equal to each other.
so 2x-20=30
and
15=3y-9
Because + and - make - which makes you left with 3-5 which equals to -2 because it gets negative.
