Answer:
a. 4x = x × 4 while x⁴ = x × x × x × x
b. when x = 2, 4x = 8 and x⁴ = 16
Explanation:
i calculated the answers for b based on the equations in a by substituting 2 into x! hope this helps and you can comment if you need any clarification :D
Answer:
x = 10/√2 ≈ 7.07
Step-by-step explanation:
Comenzaremos por dividir el triángulo en dos partes y definir H, como en la figura adjunta.
Aplicando el teorema de Tales, sabemos que:

También sabemos que, dado que el tirángulo menor es la mitad que el triángulo mayor, la relación entre áreas es:

Dado que formamos dos triángulos rectángulos, podemos despejar el valor de H como:

Podemos entonces despejar x de la siguiente manera:

To solve this problem, you have to use a proportion:
7/20 = x/100
After setting up the proportion, you have to cross multiply:
20x=700
Now, solve the equation by dividing by 20 on both sides:
x=35
So Charles has 35 laps left.
I think the answer is 02 + 8x +8x + 48
