If you are like most people you may think abuse is physical violence – having force used against you, having bones broken, being attacked, punched or kicked.  This is true of course, but other types of abuse exist which are as bad as, and can be worse than, physical violence.  There are four types of child abuse; physical, sexual, psychological, physical and emotional neglect.  Although listed as five distinct categories they all over lap.

Step-by-step explanation:

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
