For 3x2 - 4x+ 1, match the following:
Usimov [2.4K]

Constant: 1

Degree: 2

Coefficient : 3 and -4

Algebraic expression: 3x^2-4x + 1

Variable : x

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

3x^2-4x + 1

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 3x^2-4x + 1 , coefficients are 3 and -4

<h3><u>Algebraic expression:</u></h3>

An algebraic expression is a mathematical expression that consists of variables, numbers and operations.

Here the algebraic expression is:

3x^2-4x + 1

<h3><u>Variable:</u></h3>

The letters x, y, and z are common generic symbols used for variables.

Thus the variable in given expression is x

inna [77]
<span>f(x)=3[x-2]
So, f(5.9) = ?
f(5.9) = 3(5.9 - 2)
=3(3.9)
=11.7 = 12
Thus, the answer is 12.

a right angle is 90°

a straight angle is 180°

an acute angle is less than 90°

is you look at the picture and the definitions you can notice that the angle is less than 90 ° hence its an <u>acute angle </u>
