Answer:
3
Step-by-step explanation:
An equilateral triangle means all sides have the same length and there are 3 sides to a triangle. Therefore, the answer is 3.

Answer:</h2><h2>The expressions that can be subtracted from 9x to result in the expression 3x+5 is 6x - 5</h2>
Step-by-step explanation:
To find the expression that can be subtracted from 9x to result in the expression 3x+5.
Let us consider the expression, a - b = c
Here a = 9x
the result, c = 3x + 5
b = ?
Substitute the values in the above equation, we get
9x - b = 3x + 5
9x - (3x + 5) = b
b = 6x - 5
If the measure of central angle is 3π /4 radians, then the area off the shaded sector is 96π square units
The radius of the circle = 16 units
The central angle of the shaded region = 3π /4 radians
The area of the sector = (θ/ 360) × πr^2
Where θ is the central angle of the sector
r is the radius of the sector
Substitute the values in the equation
The area of the sector = ((3π /4) /360) × π × 16^2
Convert the radians to the degrees
= (135/360) × 256π
Multiply the terms
= 96π square units
Hence, the area of the shaded sector is 96π square units
The complete question is

Step-by-step explanation:
Given

i.e. first to fifth
Required
Determine number of selection
1st position = Any of the 30 students
2nd position = Any of the 29 students
3rd position = Any of the 28 students
4th position = Any of the 27 students
5th position = Any of the 26 students
Number of selection is then calculated as:
