4. which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − 8x3 3 6x2 − 6x 5
CaHeK987 [17]
ANSWER

The algebraic expression that is a polynomial with a degree of 2 is
6 {x}^{2}  - 6x + 5



EXPLANATION

The degree of a term of a polynomial is the total sum of the exponents of the variables in each term.


The highest degree of the polynomial is considered the degree of the polynomial.



For first option,
4 {x}^{3}  - 2x + 10
the highest degree is 3.



The second option is,
{x}^{2}  - 8 {x}^{3}  + 3
This polynomial also has a degree of 3.



The third option is,
6 {x}^{2}  - 6x + 5
This last option has a degree of 2.


Therefore the correct answer is option C.

Which choice is equivalent to the quotient below shown here when x&gt;0?
qwelly [4]

Answer:

Choice B is correct

Step-by-step explanation:

The given radical division can be expressed in the following form;

\frac{\sqrt{16x^{3} } }{\sqrt{8x} }

Using the properties of radical division, the expression can be expressed in the following form;

\sqrt{\frac{16x^{3} }{8x} }=\sqrt{2x^{2} }

Simplifying further yields;

\sqrt{2x^{2} }=\sqrt{2}*\sqrt{x^{2} }=x\sqrt{2}

Choice B is thus the correct alternative

A basketball court has a rectangular shape with a length of 94 feet and a width of 50 feet. Janet made two scale models if the r
Irina-Kira [14]

Answer:

Step-by-step explanation:

Note that there are two scale models with each of ratio of 1/2 and 1/16 respectively.

For the first model, the dimension will be as follows:

Length/2 by width/2

94/2 by 50/2 = 47 feet by 25 feet.

For the second model, the dimension will be as follows:

Length/16 by width/16

The dimensions of the second model is 94/16 by 50/16 = 5.875 feet by 3.125 feet.

Since we are to solve for the area of the smallest scale model which is

5.875 feet by 3.125 feet.

Hence, area (A) = L× W

=5.875 × 3.125 feet.

= 18.359ft^2
