The Width is 2 1/4, 2.25 :) Explanation: *You have to divide the area by the given number* (Important rule) So you have to do 7 7/8 divided by 3 1/2, to do that, turn both whole number fractions into improper, once you did that, you change the division sign to Multiplication, then you flip the Second fraction, then multiply Straight across. Did you get 2 1/4? :)

  1. Substitute in <em>x</em>:                    g(1) = 3(1) - 2
  2. Multiply:                               g(1) = 3 - 2
  3. Subtract:                              g(1) = 1

<u>Step 3: Find f[g(1)]</u>

  1. Substitute in g(1):                    f[g(1)] = 2(1) + 1
  2. Multiply:                                   f[g(1)] = 2 + 1
  3. Add:                                         f[g(1)] = 3
