Professor Turner wrote the expression below on the chalkboard for histeam at the Research Center. He asked the scientists there to write an equivalent expression that eliminated the parentheses. 3(4 x+6 y+2 z)+4(x-z) 1. Write the equivalent expression. 2. Which math properties should the scientist use to completeProfessor Turner's task? Explain. 3. Three scientists presented the following solutions to Professor Coke-which of them properly applied the math property you described above? Explain \text { - Dr. Oumou Diarrah wrote } 12 x+18 y+6 z+4(x-z) \text { - Dr. Camron Jones wrote } 2(9 x+2 y-z) \text { - Dr. Dalena Spencer wrote } 18 x+18 y+6 z 4. Using the new expression, x equals the absolute value of -3 times20% of the value of y. Y equals 25% more than the value ofz, and z equals 100. Solve the above equation from Professor Coke.
