Joslyn wants buy 4 packs of pens for $12.00 each and a pack of pencil for $6.00 how much money does she needs

answer: haha (: i’ll go see what it is

step-by-step explanation:

207/8 is the 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

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
