19. Avery is buying cupcakes for 12 friends at the mchool bake sale. Each cupcoke costs \( \$ 1.25 \), Mowon A. Write an expression using the Otstributive Property to find the total cost of 12 cupcakes. B. If Avery has \( \$ 24 \), how much money will he have left? Solve for \( r \). \[ 33 r=9.9 \] \( r=\frac{\square}{\frac{\square}{\square}} \) Find Derivative \( h(t)=\left(\frac{t^{2}}{t^{3}+2}\right)^{2} \) \( \left. \begin{array} { l } { ( g \cdot f ) ( x ) : } \\ { f ( x ) = 4 x } \\ { g ( x ) = x ^ { 3 } + 3 x ^ { 2 } + 2 x - 8 } \end{array} \right. \) Solve for \( n \), \( 3.5=2.5 n \) \( n= \) \( \left. \begin{array} { c } { ( f / g ) ( x ) } \\ { f ( x ) = x ^ { 2 } + 8 x + 16 } \\ { g ( x ) = x + 4 } \end{array} \right. \) Solve for \( c \) \[ \begin{array}{c} \\ 6.3=\frac{c}{1.5} \\ c=\square\end{array} \] 17. Savannah is choosing between two cell phone plans. Plan \( A \) charges \( \$ 60 \) a month plus a one time activation fee of \( \$ 75 \). Plan 8 charges \( \$ 63 \) a month plus a one-time activation fee of \( \$ 15 \). Evaluate the expressions \( 60 m+75 \) and \( 63 m+15 \) when \( m=18 \) to find the total cost for each cell phone plan for 18 months. What is the difference in cost between the two cell phone plans? flesson 4\( ) \) The area of the rectangle is given. Factor out the GCF to find expressions for the missing dimensions. Find expressions for the missing dimensions. \( \square \) (Simplify your answer. Use a comma to separate answers as needed.) Solve for \( c \) \[ \frac{c}{5}=8 \] \( c=\square \)
