A pet home owner wants to keep the ratio of cats to dogs at 3:5. She has 21 cats, how many dogs are there in the pet home?

There are 35 dogs in the pet home.

Step-by-step explanation:

3:5 is the ratio, 3 being cats and 5 being dogs

Since there are 21 cats, you would do 21/3 to find the ratio value - which is 7

Now, multiply 5 times 7 to get the amount of dogs, which is 35.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
