Julie wants to make a drawing that is 1/4 the size of the original drawing. Sahil makes a drawing that is 1/3 the size of the original. A tree in the original drawing is 12 inches tall. How many inches different will there be between the height of the tree in Julie’s and Sahil’s drawing?

a tree=1/4 5=d

Step-by-step explanation:

12 inches tall

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
