Step-by-step explanation:

Step 1: Define

f(x) = 4x - 1

f(1) is x = 1

Step 2: Evaluate

Substitute in x [Function]:                                                                              f(1) = 4(1) - 1Multiply:                                                                                                           f(1) = 4 - 1Subtract:                                                                                                          f(1) = 3

x =

Step-by-step explanation:

The outer and inner triangles are similar, thus the ratios of corresponding sides are equal, that is

= , that is

= ( cross- multiply )

18x = 96 ( divide both sides by 18 )

x = =
