Final answer:
To find the value of the expression y(1+z)+6 when y=2 and z=2, substitute the given values and solve the expression.
Step-by-step explanation:
To find the value of the expression y(1+z)+6, substitute the given values of y and z into the expression. In this case, y = 2 and z = 2.
So, the expression becomes 2(1+2)+6. First, solve the parentheses by doing the addition inside, 1+2 = 3.
Then, multiply 2 by 3 to get 6. Finally, add 6 and 6 to get the final answer, which is 12.
