Answer:
Step-by-step explanation:
Limit refers to the value that the function approaches as the input approaches some value.
We say
, if f(x) approaches L as x approaches 'a'.
(a)



(b)


The negative solution is x = –1.
Solution:
Let the number be x.
Square of a number = x²
3 times a number = 3x
Difference of square of a number and 4 = 3 times that number

Subtract 3x from both sides of the equation, we get

–3x can be written as x – 4x.


1st bracket have common term x and bracket have –4 common term.

Take common term x + 1 outside.

<em>By zero factor principle, if AB = 0 then A = 0 or B = 0.</em>
x + 1 = 0, x – 4 = 0
x = –1, x = 4
The negative solution is x = –1.
Answer:
A central angle of a regular polygon is an angle whose vertex is the center and whose sides contain two consecutive vertices of the polygon. You can divide 360° by the number of sides to find the measure of each central angle of the polygon.
