In the expression$$axn identify which letters go with each vocabulary word "a" is the exponent, "x" is the coefficient, "n" is the base
"a" is the coefficient, "x" is the base, "n" is the exponent
"a" is the coefficient, "x" is the exponent, "n" is the base
"a" is the base, "x" is the coefficient, "n" is the exponent

the correct answer is a.) bc< mn 5 stars if this you : )

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
