\huge \sf༆ Answer ༄

Let's solve ~

  • \sf {x}^{2}  - 10xy + 21 {y}^{2}

  • \sf {x}^{2}  - 7xy - 3xy + 21 {y}^{2}

  • \sf x(x - 7y) - 3y(x - 7y)

  • \sf( x - 7y)(x - 3y)

Hence, the correct choice is ~ A

If bob makes 40 mintues of long distance call for the month, which plan cost more
lora16 [44]

First, look at the x axis (this is the one labeled Minutes Used per month)

Find the number 40, then look at where the lines meet on that line. The red line for Plan B it’s at 8 dollars. The blue line for Plan A is at 4 dollars.

Plan B costs more.

To find the difference, subtract 4 from 8.

$8 - $4 = $4

Plan B costs 4 dollars more than Plan A.

If you have any further questions feel free to ask.

Hope this helps.

Write the equation of the circle graphed below
Norma-Jean [14]

Answer:

The equation of the circle is

(x + 2)² + (y + 2)² = 9

Centered at (-2, -2), with radius of 3 units.

Step-by-step explanation:

The general equation of a circle is given as

(x - h)² + (y - k)² = r²

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

Looking at the graph, the center is the red dot. It corresponds to -2 on the y-axis, and -2 on the x-axis. So, the center (h, k) is (-2, -2).

The radius is the distance from the center of the circle to the edge of the circle. The red dot is the edge of the circle, there are 3 lines that represent 3 units, so we have a radius of 3 units.

Using these in the general equation, we have

[x - (-2)]² + [y - (-2)]² = 3²

(x + 2)² + (y + 2)² = 9

And this is the equation.

On a coordinate plane the coordianits of vertices the and t for a polygon are r(-7,3) and r (3,3) what is the length of side rt
NemiM [27]

The length is 10.


Since the two points share the same y-coordinate, the segment rt is horizontal.


This means that the length of the side is simply the difference (in absolute value) between the x coordinates of the two points.


So, we have


\overline{RT} = |-7-3| = |-10| = 10
