See explanation below

Step-by-step explanation:

The degree of a polynomial is the LARGEST power at which the variable/s appear in their expression.

Notice that in the given polynomial, the highest power for the variable x is 3, from the term 5 x^3.

There is no other term with higher power for x.

Answer:

w = 312

The step by step process of rearranging the equation to find w is as follows:

w / -8 = -39

Multiplying both sides by –8:

w / -8 x -8 = -39 x -8

w = 312

Simplify each square root expression. Describe the simplified form of the expression as rational or irrational. In your final an

expeople1 [14]

Answer:

Part 1) 11 is a rational number

Part 2) $4\sqrt{3}$ is a irrational number

Step-by-step explanation:

we know that

A <u><em>Rational Number</em></u> is a number that can be made by dividing two integers

Part 1) we have

$\sqrt{121}$

we know that

$121=11^{2}$

substitute

$\sqrt{11^{2}}=(11^{2})^{\frac{1}{2}}=(11)^{\frac{2}{2}}=11$

Is a rational number, because i can express the number 11 as the ratio of two integers (as example 11/1)

Part 2) we have

$\sqrt{48}$

we know that

$48=2^{4}(3)$

substitute

$\sqrt{2^{4}(3)}=(2^{4}(3))^{\frac{1}{2}}=4\sqrt{3}$

Is a irrational number, because cannot be expressed as the ratio of two integers
