1 answer:

8 0

4+2(x+3) first do the distributive property.
4+2(x)+2(3)
4+2x+6 then add like terms
4+6
2x+10 then divide to isolate the variable (inverse prop)
(2x/2) + (10/2)
x=5

Simplify: (2x – 3)2 4x2 + 9 4x2 – 12x + 9 4x2 – 12x + 6 4x2 – 6

Alexxandr [17]

Answer:

$4x^2-12x+9$

Step-by-step explanation:

we have

$(2x-3)^2$

we know that

$(a-b)^2=a^2-2ab+b^2$

In this problem

$a=2x\\b=3$

substitute in the formula

$(2x-3)^2=(2x)^2-2(2x)(3)+(3)^2$

$(2x-3)^2=4x^2-12x+9$

Luis es repartidor de leche el tiene 534 bolsas y las reparte entre cierto numero de tienda de modo que a cada le corresponde 28

OlgaM077 [116]

The first thing we must keep in mind is that there are 2 bags left over.
Therefore, Luis distributed:
534-2 = 532
The number of bags will be:
N = (total amount distributed) / (amount distributed per store)
Substituting we have:
N = (532) / (28)
N = 19
Answer:
Luis distributed milk for 19 stores.
