I believe the correct answer would be A.

I assume this because compared to the other given options, this method would target the most diverse audience.

Sample A will be a good choice.

It has students from all classes and all subjects.

All other options don't guarantee that they have students from all possible subjects.

Answer:

$x^{2} + 5x - 10 = 0 \\x^{2} + 5x = 10 \\ x(x + 5) = 10$

Now,

Either,

x=10

Or,

If you multiply 2 xr you will get the * -radius -circumference -diameter -area

Komok [63]

Answer:

Diameter

Step-by-step explanation:

Variable r stands for radius.

The radius is half of the length within the circle from the two farthest points.

Multiplying this radius will get you the diameter, which is the full length (instead of half) within the circle from the two farthest points.

Pls help with algebra!

Serjik [45]

Part A: This data does represent a function because no value of x is repeated.
Part B: If x = 6 for the relation f(x) = 7x - 15, then f(x) will equal 27. The function f(x) = 7x - 15 will have the greater value
Part C: If f(x) is equal to 6 then x will equal 3

Find the measure of the exterior angle.

Illusion [34]

Answer:

108 degrees

Step-by-step explanation:

From the diagram we are given

Interior angles are 2x + 1 and 63 degrees

Exterior angle = 5x -2

The sum of interior angles is equal to the exterior angle

2x + 1 + 63 = 5x - 2

2x + 64 = 5x - 2

2x - 5x = -2-64

-3x = -66

x = -66/-3

x = 22

Get the exterior angle:

Exterior angle = 5x-2

Exterior angle = 5(22) - 2

Exterior angle = 110-2

Exterior angle = 108 degrees

Hence the measure of the exterior angle is 108 degrees
