PLEAS HEL. PLEASE PLEASE PLEASE. Please provide answers for both a and b WITH AN EXPLANATION...THANK YOU SOO MUCHHH 16. State the degree of each function and whether each is linear, quadratic or neither.

a) f(x)=(x-2)(x+2)

b) f(x)= 3(x + 2)^2 – 3x^2

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

3,000,540

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
