Constant: 1
Degree: 2
Coefficient : 3 and -4
Algebraic expression:
Variable : x
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
We have to find the constant, degree, coefficient , algebraic expression and varibale
<h3><u>Constant:</u></h3>In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number like 1, 2
In the given expression, constant is 1
<h3><u>Degree:</u></h3>The largest exponent the variable has in a polynomial with one variable
In the given expression, largest exponent is 2
Thus degree of polynomial is 2
<h3><u>Coefficient:</u></h3>The coefficients are the numbers that multiply the variables or letters
In , coefficients are 3 and -4
An algebraic expression is a mathematical expression that consists of variables, numbers and operations.
Here the algebraic expression is:
The letters x, y, and z are common generic symbols used for variables.
Thus the variable in given expression is x
Answer:
Step-by-step explanation:
Since ABC is an equilateral triangle, thus AB=BC=AC=x, therefore
The perimeter of ΔABC=36
⇒AB+BC+AC=36
⇒x+x+x=36
⇒3x=36
⇒x=12
Thus, AB=BC=AC=12.
Now, Since ΔADC is isosceles triangle, therefore AD=DC=y.
Perimeter of ΔADC=40
⇒AD+DC+CA=40
⇒x+y+y=40
⇒12+2y=40
⇒2y=28
⇒y=14
Therefore, AD=DC=14
Thus, Length of sides of ΔABC are AB=BC=AC=12 and Length of sides of ΔADC are AD=DC=14.
