Answer:

1. The missing value is 9

2. The missing value is 81

Step-by-step explanation:

1. To find the missing value of a perfect square you divide the center term (-6 as is -6x) by two to get 3 then square the three to get 9

To check this write it as the simplified form (x-3)^2 and multiply it out again using foil.   x times x is x^2,  -3 times x is -3x ( this happens twice adding up to the -6x), and -3 times -3 is 9 making it x^2 -6x +9

2. Follow the steps for the previous problem to get the same answer for this one. Divide 18 (middle term) by 2 making 9. Then square the 9 making 81.

Dos amigos tienen lapices bordadores y tajadores en su cartuchera hay 8 borradores en total Mónica tiene el doble de lápices q F
aalyn [17]

Answer:

Mónica tiene 5 sacapuntas, 10 lápices y no borradores, mientras que Felipe tiene 5 lápices, 10 sacapuntas, 8 borradores

Step-by-step explanation:

El número total de borradores = 8

La cantidad de lápices que tiene Mónica = 2 × La cantidad de lápices que tiene Felipe

El número de sacapuntas que tiene Mónica = El número de lápices que tiene Felipe

El número de sacapuntas que tiene Felipe = 5 + El número de lápices que tiene

El número de suministros que tiene Monica = 18

El número de goma de borrar que tiene Monica = 0

Sea x el número de sacapuntas que tiene Monica, obtenemos;

El número de lápices que tiene Felipe = x

El número de sacapuntas que tiene Felipe = 5 + x

El número de lápices que tiene Monica = 2 · x

El número total de suministros que tiene Monica = x + 2 · x = 18

∴ x = 18/3 = 6

El número de sacapuntas que tiene Monica = 5

El número de lápices que tiene Monica = 2 · x = 2 × 5 = 10

El número de gomas de borrar que tiene Monica = 0

El número de lápices que tiene Felipe = x = 5

El número de sacapuntas que tiene Felipe = 5 + x = 5 + 5 = 10

El número de gomas de borrar que tiene Felipe = 8.
