We have the following expression given:

We can start selecting as common factor 4y^2 and we got:

Now we can select y+7 as common factor and we got:

So then our final answer would be:
The answers are x=7 or x=-2

<u>+</u>

/2
x=5 <u>+</u>

/2
x=5 <u>+</u>

/2
x=5 <u>+</u>

/2
x=5 +

/2.....x=7
or
x=5 -

/2....x=-2
Answer:
y - 0.5x
Step-by-step explanation:
Given that the dog eats the same amount of food each day and on day 3, the available quantity of food
= 12 pounds
On day 7 (4 days after), the available quantity of food is 10 pounds. The difference in the amount of food in 4 days
= 12 - 10
= 2 pounds
This means that each day, the amount of food eaten by the dog in one day
= 2/4
= 0.5 pound
Hence the amount of dog food in the bag y for any day after opening the dog food x will be given as
= y - 0.5x
Answer:
6x^3+2xy+3x^2y+y^2
