At birth, a puppy weighed 5.5 ounces. When it was adopted 9 weeks later, its weight was 3.5 times its birth weight. What was the puppy’s weight when it was adopted? 17.05 ounces 19.25 ounces 170.5 ounces 192.5 ounces

b.an increase in a causes b to decrease

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

-2x-4
