Step-by-step explanation:
<u>Volume And Function
s</u>
Geometry can usually be joined with algebra to express volumes as a function of some variable. The volume of a parallelepiped of dimensions a,b,c is

Our problem consists in computing the volume of a box made with some sheet of metal 12 ft by 18 ft. The four corners are cut by a square distance x as shown in the image below
.
If the four corners are to be lifted and a box formed, the base of the box will have dimensions (12-2x)(18-2x) and the height will be x. The volume of the box is

Operating and simplifying

Answer:
12,13,15,16 i believe
Step-by-step explanation:
De acuerdo con un sistema de ecuaciones, tiene-se que los números son 31 y 84.
----------------
- En el sistema de ecuaciones, tiene-se que los números son x e y.
- Suma de 115, o sea,

- <u>El número mayor es dos veces más 22 unidades que el otro</u>, o sea,

----------------
Primero se encuenta el número menor, <u>reemplazando la segunda ecuación en la primera:</u>





----------------
El número mayor es dado en <u>función de el menor</u>, o sea:

Los números son 31 y 84.
