To solve for this, we need to find for the value of x
when the 1st derivative of the equation is equal to zero (or at the
extrema point).
So what we have to do first is to derive the given
equation:
f (x) = x^2 + 4 x – 31
Taking the first derivative f’ (x):
f’ (x) = 2 x + 4
Setting f’ (x) = 0 and find for x:
2 x + 4 = 0
x = - 2
Therefore the value of a is:
a = f (-2)
a = (-2)^2 + 4 (-2) – 31
a = 4 – 8 – 31
a = - 35
1.) a.) 12 / 6 = 2
b.) 3 / 2 = 1.5
c.) 16 / 8 =2
d.) Positive
2.) 0 = 0
2 = 13
4 = 26
6 = 39
8 = 52
10 = 65
a.) $6.50
b<span>.) Is increasing
c.) </span>Positive
- - = + 9-(-4)= 9+4 so minus minus becomes plus. and 13 is the answer.
x = 1

In the second figure, VP is the bisector of 
The measure of MN from the diagram is 6
<h3>Similarity theorem of triangles</h3>
From the given triangle, the expression below is true;
ML/LK = MN/NO
Given the following parameters
ML = 4
LK = 10
NO= 15
Substitute the given parameters into the formula
4/10 = MN/15
Cross multiply
10MN = 4 * 15
10MN = 60
MN = 6
Hence the measure of MN from the diagram is 6
