Explain how algebra tiles represent like terms and zero pairs
love history [14]

Answer:

Suppose the two like terms are 2 x and 3 x.So to Represent them with algebra tiles ,

Here shape of tiles = Either Square or rectangle

For example , 2 x=Draw two tiles of same color mark variable  x in front of it.For, different values of x, we get different number of total tiles.

3 x= Draw three tiles of same color and mark variable  x in front of it.For, different values of x, we get different number of total tiles.

For , Polynomial, 3 x -3,

Draw three tiles representing same color, Mark x over it, and then put negative sign in front of it, and draw three tiles of any other color.

To represent Zero,

We can write it as, x -x or p-p

Draw two tiles of same color , and mark negative sign in between .

General formula: A x - A x

Draw A tiles of same color, twice.And mark negative sign in between.

The equation of a circle is given below.
Nataliya [291]

Answer:

(h,k) = (32,-4)

r = 32

Step-by-step explanation:

The general equation for a circle is given by:

(x-h)^2+(y-k)^2=r^2   (1)

where (h,k) is the center of the circle and r is the radius.

You have the following equation:

x^2+(y+4)^2=64x   (2)

You first need to complete squares in order to obtain an equation of the form (1). Thus, you have that the second term must be in a perfect square trinomial:

2b = 64

b = 32

Then, you have to sum 32^2 and also subtract the same number in the expression (2):

x^2-64x+(y+4)^2=0\\\\(x^2-64x+32^2)+(y+4)^2-32^2=0\\\\(x-32)^2+(y+4)^2=32^2

you compare the last result with expression (1) and obtain that the raiuds of the circle is r = 32

Furthermore, the center of the circle is (h,k) = (32,-4)
