What is x+3(x-2)-6 simplified?

In the diagram, gef and hef are congruent. what is the value of x

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)

Jennifer graphs the function f(x)=x squared. then she graphs the function f(x-3). how does the graph f(x-3) differ from the graph of f(x)
