The perimeter of a rectangular yard is 204 feet. If the width of the yard is 45 feet, what is the length of the yard?

c) Escribe los primeros seis términos de la sucesion y verifica que las segundas diferencias sean constantes. i. Términos: ii. Primera diferencia: ii. Segunda diferencia:

If \( f(x)=-3 /(x+2)+1 \) what will the asymptotes be?

Perform the operations. Then simplify, if possible. \[ \begin{array}{l}\frac{1}{(t-4)(t+4)}-\frac{6-t}{(t+4)(t-4)} \\ \frac{1}{t^{2}-4 t+16} \\ \frac{-t+5}{t^{2}-4 t+16} \\ 0 \frac{t-5}{t-4} \\ 0 \frac{t-5}{(t+4)(t-4)} \\ \frac{-t+5}{t-4}\end{array} \]

Select all ratios equivalent to \( 1: 2 \). \( 20: 10 \quad 8: 16,16: 24 \)

7) cual es el valor de \( \frac{4}{5}-\frac{1}{3}-\frac{1}{15}= \) ? \( \begin{array}{llll}\text { A) } \frac{1}{5} & \text { B) } \frac{2}{5} & \text { C) } \frac{4}{15} & \text { D) } \frac{7}{15}\end{array} \)
