<h3><u>Question:</u></h3>
Which property was used to simplify the expression?
3c+9+4c=3c+4c+9
distributive property
commutative property
associative property
inverse property
<h3><u>Answer:</u></h3>
Commutative property of addition is used
<h3><u>Solution:</u></h3>
Given that,
3c + 9 + 4c = 3c + 4c + 9
We have to find the property used here
The property used is commutative property of addition
<em><u>Definition:</u></em>
Commutative property of addition means that numbers can be added in any order and we will still get the same answer
This means that,
a + b + c = a + c + b
It doesnt matter which is added first, we will still get the same answer
Therefore,
3c + 9 + 4c = 3c + 4c + 9
7c + 9 = 7c + 9
Thus commutative property of addition is used
Answer:
Therefore, ( 1 , 1 ) is the Solution to the Given Equations
Step-by-step explanation:
Given:
..............Equation ( 1 )
..............Equation ( 2 )
To Find:
x = ?
y = ?
Solution:
..............Equation ( 1 )
..............Equation ( 2 )
Substituting equation 1 in equation 2 we get
Substituting 'x' in Equation ( 1 ) we get
Therefore, ( 1 , 1 ) is the Solution to the Given Equations
Answer:
Step-by-step explanation:
This construction shows how to draw the perpendicular bisector of a given line segment with compass and straightedge or ruler. This both bisects the segment (divides it into two equal parts, and is perpendicular to it. It finds the midpoint of the given line segment.

There are two "special" right triangles:
isosceles 45°-45°-90° triangle with sides in the ratios 1 : 1 : √2
30°-60°-90° triangle with sides in the ratios 1 : √3 : 2
These side lengths give rise to the trigonometric ratios shown below for angles with 30°, 45°, or 60° as reference angles.
