Question \#13 Vivian went on a bicycle trip through Germany with her family. One afternoon, she rode her bicycle alc a long, flat road at a constant speed for 24 kilometers (km). The ride took her 2 hours \( (\mathrm{h}) \). At what spee did she ride her bicycle?

Para el siguiente Patalelepipedo con coordenadas \( A(+2,+2) \), \( B(+6 \) dh \( C(+6,+5), D(+2,+5),(+8,+7), F(+4,+7), 6(+4,+4) \) y \( H(+8,+4) \), gratricar en plano cartesiano. calcular distancias delados, perimetro, area y volumen.

Solve for \( d \) \( 10 d-6 d=4 \) \( d=\square \)

4. Given \( f(x)=x^{2}-49 \), Find \( \frac{f(x+h)-f(x)}{h} \)

Read through the solution below. Then, answer the questions that follow. \( \frac{a}{b}+\frac{c}{d}=e \) \( \frac{a}{b}=e-\frac{c}{d} \) \( \frac{a}{b}=\frac{[b o x]}{d} \) \( a d=b(d e-c) \) \( \frac{a d}{d e-c}=b \)

Indique el grado relativo a " \( y^{n} \) en el polinomio homogénen: \[ P(x ; y)=8 x^{2 n+6}-3 x^{2 n+3} y^{n+2}+5 y^{9-n} \]
