About 8 out of 15 homes have a dog as a pet. On a street with 165 homes, how many would you expect to have a dog for pets? Please explain how you got your answer.

88

Step-by-step explanation:

create a proportion:

8/15 = x/165

cross-multiply:

15x = 1320

x = 88

Step-by-step explanation:

200 because dogs are important animals

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
