A
Don't forget that you can also pull out an x besides the 10. The expression should look like this.
A(x) = 10x(x - 5)
The GCF is 10x
B
The area of the Bedroom = 10x ( x - 5)
If the length = 5x then the width is
A/L = 10x (x - 5)/(5x)= 2*(x - 5)
C
Now they are changing the Length to the GCF. We determined in A that the GCF = 10x
This time A/L = 10x(x - 5)/10x = (x - 5)
So the width = x - 5

Responder:
Copias del libro A = 50
Copias del libro B = 70
Explicación paso a paso:
Costo por libros A = 200
Costo por libro B = 150
Sea el número de libros A = x
Número de libros B = y
Número total de libros comprados = 120
Costo total = 20,500
x + y = 120 - - - (1)
200x + 150y = 20500 - - - (2)
De 1)
x = 120 - y
Sustituya x = 120-y en (2)
200 (120 - años) + 150y = 20500
24000 - 200y + 150y = 20500
24000 - 50y = 20500
-50 años = 20500 - 24000
-50y = - 3500
y = 70
x = 120 - y
x = 120 - 70
x = 50
