Your favorite dog groomer charges according to dog's weight. If your dog is 15 pounds or less the groomer charges. $35. If your dog is more than 15 but less than 40 pounds, she charges $40. If your dog is 40 pounds or more, she charges $40. plus an additional $0.50 for each pound more than 40. write a piecewise function​

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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
