Competencia a evaluar: Usa el concepto de semejanza para resolver triángulos. En un triángulo rectángulo ABC de catetos AB=12cm y AC=16cm se traza DE= 4cm perpendicular a la hipotenusa (con D sobre la hipotenusa y E sobre AC). Calcular las medidas de todos los lados de los triángulos ABC y CDE, usando solo el concepto de semejanza (plantee las ecuaciones o justifique sus respuestas usando solo semejanza).

answer: i think one of the answer is $150 and $300?

step-by-step explanation:

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
