Addison uses up all the dog food in 6 days. each day, she feeds her dogs
the same amount of food. between which two numbers is the number of
cups of food she feeds her dogs each day? there are 31 cups of dog food.
a. o and 1
b. 1 and 2
c. 5 and 6
d. 6 and 7

Step-by-step explanation:

She uses all the food to feed the dogs in 6 days. She feeds the with an equal amount of food in 6 days. This means that whatever amount of food she buys, the least amount she would feed the dogs with is 1/6 of that amount.

There are 31 cups of dog food. This means that the amount she would feed them with each day is

1/6 × 31 = 5.1 cups

So the least amount is 5 cups

Therefore,

The number of cups she feeds her dogs with would be between 5 and 6 cups.

Step 2: (x + 4)(x + 2) = 8

Step-by-step explanation:

x2 + 6x + 8 = 0

x2 + 4x + 2x + 8 = 0

x(x + 4) + 2(x + 4) = 0

(x + 2)(x + 4) = 0
