Disegnare le rette di equazione: a. \( y=3 x-5 \) b. \( x+2 y-4=0 \) c. \( x=-3 \) d. \( y=1 \) Capire se le coppie di rette a.-b. e c.-d. sono parallele, perpendicolari incidenti.

Na figura está representado um cubo. Determina a medida da aresta, em centímetros, 7.1. a área da superficie total do cubo for \( 726 \mathrm{~cm}^{2} \);

. Wi. Re. Lesson ao d. The figures shown are regular pentagons, meaning that each pentagon has five sides that are the same length. If a side length of figure 1 is 40 units, what is the length of the corresponding side of figure 3 ?

Write an equation that represents the relationship between the side lengths of figure 1, Let \( y \) represent a side length of figure 3 , and let \( x \) represent the corre length of figure 1 .

a. Is figure 3 a scale drawing of figure 1 ?

\( \angle A C X \cong \angle B D X \) (G) \( \angle A C X \cong \angle B X D \) (1) \( \angle A C X \cong \angle D X B \) (1) \( \angle A C X \cong \angle D B X \)
