C) The 2 triangles are similar , then we can write:
5x/45 = 20/36 . Cross multiplication:
5x*36 = 45*20
180x = 900 and x = 900/180 , x = 5 (and 5x = 25)
d) Remember the proportionality theorem (or Thales')
You can write the following proportion:
GH/HJ = KL/LM
8/6 = 10/x . Cross multiplication:
8x = 60 and x = 60/8 , x = 7.5
To factor an expression:
1: find a common factor
2: divide a common factor by a term
3: divide any other terms after putting in parenthesis
4: simplify

Answer:
<h3>Two of the sides of triangle KNM are the equal</h3>
Step-by-step explanation:
From the triangle KNM, we can see that two of the angles M K N and Angle N M K are the same. If two of the angles are equal this means that two of the sides of the triangles are also equal. This type of triangle is known as an ISOSCELES TRIANGLE.
An isosceles triangle is a triangle that has two of its angles and sides to be equal.
B= -2x+5-2x^2-ax
A= -2x+5-2x^2-b/x
x=0
