Write in factored form by factoring out the greatest common factor (or a negative common factor if the coefficient of the te te of greatest degree is negative). \( a ( y - 3 ) + z ( y - 3 ) \) 

Read the following description of a relationship: At every company meeting, the president speaks for 19 minutes and then takes questions from her employees. Let \( q \) represent the number of minutes she spends answering questions and \( t \) represent the total number of minutes the meeting lasts. Use the function \( t=q+19 \) to find the value of \( t \) when \( q=6 \). \( t=\square \)

Read the following description of a relationship: \[ \begin{array}{l}\text { An electronics store has } 18 \text { permanent employees who work all year, The store } \\ \text { also hires some temporary employees to work during the busy holiday shopping } \\ \text { season. } \\ \text { Let a represent the number of temporary employees and } b \text { represent the total } \\ \text { number of employees during the holiday shopping season. }\end{array} \] Use the function \( b=a+18 \) to find the value of \( b \) when \( a=7 \).

Read the following description of a relationship: \[ \begin{array}{l}\text { Whitney has a superhero lunch box collection with } 20 \text { lunch boxes in it. From } \\ \text { now on, she decides to buy one new lunch box every year for her birthday. } \\ \text { Let } y \text { represent the number of years from now and } b \text { represent the total number } \\ \text { of lunch boxes in her collection. }\end{array} \] Use the function \( b=y+20 \) to find the value of \( b \) when \( y=1 \). \( b=\square \)

Solve \( \sqrt{2 x}=x-4 \)

Charlotte rides the bus 8 minutes every day. Let \( d \) represent the number of days and \( m \) represent the total number of minutes Charlotte spends on the bus. Use the function \( m=8 d \) to find the value of \( m \) when \( d=4 \). \( m=\square \)
