Estimate the question<br><br> 19.9×5.8≈
ankoles [38]

Hello :D

To work this out you need to round the numbers to a whole number.

19.9 = 20

5.8 = 6

20 x 6 ≈ 120

I hope this helps :)

Quick Answer

(fog)(x) = 2x + 6

(gof)(x) = 2x + 3

Expert Answers

f(x) = 2x

g(x) = x + 3

First let us find (fog)(x)

(fog)(x) = f(g(x)

            = f(x+3)

              = 2(x+3)

              = 2x + 6

==> (fog)(x) = 2x + 6

Now let us find (gof)(x):

(gof)(x) = g(f(x)

           = g(2x)

          = 2x + 3

==> (gof)(x) = 2x + 3
