Since the maximum exponent of x is 3, there should be three roots.
Unless you have a root squared and multiplyed by a different root, you will only have two roots since two are the same.
Also, if all three roots are the same, you only have one root.

Rectangle ABCD is reflected over the y-axis. What rule shows the input and output of the reflection, and what is the new coordin
Vitek1552 [10]

Solution:

As given Rectangle ABCD is reflected over the y- axis.

When a shape or geometrical figure is reflected through a line it's distance that is distance of image from line and distance of Pre-image from that line is always same.Also perpendicular distance of vertices of any polygon that is considered for reflection has same distance from that line after reflection and before reflection.

Suppose the coordinate of A be (x,y) and considering Rectangle A B CD lie in first quadrant then when it is reflected through y - axis that is through the line x=0, it's new coordinate will become A' (-x,y).

If rectangle is in second quadrant having Vertices that is vertices of A (-x,y) then reflected over line that is x=0,→ y axis then Vertices of A' (x,y).

If rectangle is in third quadrant having Vertices that is vertices of A (-x,-y) then reflected over line that is x=0,→ y axis then Vertices of A' (x,-y).

If rectangle is in fourth quadrant having Vertices that is vertices of A (x,-y) then reflected over line that is x=0,→y axis then Vertices of A' (-x,-y).

Chicken cuties are on sale for 3.48 per pound How much will it cost to but 3.5 pounds
kramer
3.48  for 1 pound

You can put it in comparison,

3.48 / 1 = x / 3.5

And then cross-multiply it,
1x = 3.48 x 3.5
x = 12.18

The two-dimensional net of a rectangular prism is shown at the left. What is the prism’s surface area? square units
Tasya [4]

Answer:

28 units²  

Step-by-step explanation:

Assume that your net has the dimensions shown below.

Its area is

2 yellow rectangles = 2(4 × 2) = 2 × 8 = 16 units²

2 grey rectangles    =  2(4 × 1) = 2 × 4  =  8 units²

2 green rectangles  = 2(2 × 1)  = 2 × 2  = <u> 4 units²</u>

                                                 TOTAL = 28 units²

The prism's surface area is 28 units².
