For work you can wear a red or blue shirt, and black or khaki pants. You own 3 red shirts, 3 blue shirts, 2 pair of black pants and 4 pair of khaki pants. Let R = red shirt and B= black pants. Find the probability of wearing a red shirt and black pants.

i dont know it

step-by-step explanation:

i dont know sorry

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

b. f(x) = –√x + 3this is the correct answer
