29. Amelia is making a scratching post for her cat. She has a rectangul prism post that is 4 inches wide by 4 inches deep by 18 inches tall, much carpet does Amelia need to go around the post without cove the top or bottom of the post?

Câu 28. Cho tam giác \( A B C \) đều cạnh \( a \), có \( A H \) là đường trung tuyến. Biết rằng \( |\overrightarrow{A C}+\overrightarrow{A H}|=\frac{a v b}{c} \). Tính \( b-c \). \( \mathrm{KQ}: \square \)

En un triángulo \( P Q R \) se prolonga \( \overline{A B}(A \quad y \quad B \) son puntos medios de \( \overline{P Q} \) y \( \overline{Q R} \) respectivamente ) hasta interceptar en \( F \) a una paralela a \( \overline{P Q} \) que pasa por \( R \). SI: \( A B=32 \) cm . ¿Cuánto mide \( B F \) ?

Sketch each triangle. Then, determine the unknown side and angles. If two solutions are possible, give both. a) In \( \triangle \mathrm{ABC}, \mathrm{AB}=15 \mathrm{~m}, \mathrm{BC}=5 \mathrm{~m} \), and \( \angle \mathrm{A}=20^{\circ} \).

Which of the following methods would not be used to prove that two triangles are congruent? A. ASA (B) SAS (C) AAS (D) SSA

Per la seguente relazione definita in \( A \), traccia il grafo che la rappresenta: \[ a \mathcal{R} b \leftrightarrow a+b \text { è un numero pari minore di } 20, A=\{a \in \mathbb{N} \mid 6<a \leq 11\} \]
