For addition, drag tiles onto the board. To form a group, place one tile on top of another.
Using the integer tiles interactive, what steps do you
need to do to evaluate the following expression?
Select two options.
-5(-2)
O Drag 5 sets of -2 tiles to the window.
O Drag zero pairs to the window.
Remove the 5 groups of -2 tiles.
Remove 5 negative tiles from the window.
Board sum: 0

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

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
