Justin is looking to purchase a mountain bike from bikes & more, walmart, or k-mart. each store sells
the bike he likes for $327.00. walmart has the bike on sale for 30% off. bikes & more has the bike on sale for $227.50. k-mart is selling them for 1/3 off the regular price. which store has the best price? what is that price after 6% sales tax?

Step-by-step explanation:

100.50 (i hope i got it right)

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
