Ineed on math. asap i am stuck on this homework problem

white = $13, double = $14

Step-by-step explanation:

Let white chocolate chip dough = x

Let double chocolate chip dough = y

Mary:      3x + 2y = 67

Darryl:   -(3x + 4y = 95)

                     -2y = -28

                  ÷-2    ÷-2  

                        y = 14

3x + 2y = 67

3x + 2(14) = 67

3x + 28 = 67

      -28  -28

3x         = 39  

÷3           ÷3  

 x         = 13

i dont have an answer

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
