Which algebraic expression is a polynomial with a degree of 3?
Irina18 [472]

Option a: 4x^{3} -\frac{2}{x}

Option b: 2y^{3} +5y^{2} -5y

Option c: 3y^{3} -\sqrt{4y}

Explanation:

The highest degree of a polynomial is the largest exponent of that variable.

Now, we shall determine the polynomial with degree 3.

Option a: 4x^{3} -\frac{2}{x}

From the expression 4x^{3} -\frac{2}{x}, the highest degree of the polynomial is 3.

Hence, 4x^{3} -\frac{2}{x} is a polynomial with a degree of 3.

Hence, Option a is the correct answer.

Option b: 2y^{3} +5y^{2} -5y

From the expression 2y^{3} +5y^{2} -5y, the highest degree of the polynomial is 3.

Hence, 2y^{3} +5y^{2} -5y is a polynomial with a degree of 3.

Hence, Option b is the correct answer.

Option c: 3y^{3} -\sqrt{4y}

From the expression 3y^{3} -\sqrt{4y}, the highest degree of the polynomial is 3.

Hence, 3y^{3} -\sqrt{4y} is a polynomial with a degree of 3.

Hence, Option c is the correct answer.

Option d: -xy\sqrt{6}

From the expression -xy\sqrt{6}, the highest degree of the polynomial is 1.

Hence, -xy\sqrt{6} is a polynomial with degree 1.

Hence, Option d is not the correct answer.

Find the value of x with the steps
Mrrafil [7]
Two sides are same so that would be isosceles triangle. So then you would add up all angles and get this equation: 180 = 38 + x + x

2x = 142

x = 71

So the value of x is 71.
