Step-by-step explanation:

18x³y⁴
205-2d
That's the expression. 205 you start with, every day, you add two, so 2*d is logical.
There is no solution to this problem
Answer:
2x+1
Step-by-step explanation:
that's a hard question
we know that g(x)= x-3
so f(g(x))= f(x-3)
we put it in the equation :
f(x-3)= 2(x-3) +7 = 2x-6+7 = 2x +1
Answer:
yes
Step-by-step explanation:
x+7>x+3
