Answer:

No it isn't

As the variable "x" has root in it which means it isn't a whole number and for a expression to be a polynomial the variable must be whole no.

Find the distance between the two points rounding to the nearest tenth (if necessary)

Andrews [41]

Answer:

The answer is

<h2>2.8 units </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-3,3) and (-1,5)

The distance is

$d = \sqrt{( { - 3 + 1})^{2} + ({3 - 5})^{2} } \\ = \sqrt{ ({ - 2})^{2} + ( { - 2})^{2} } \\ = \sqrt{4 + 4} \\ = \sqrt{8} \: \: \: \: \: \: \: \: \\ = 2 \sqrt{2} \: \: \: \: \: \: \\ = 2.82842$

We have the final answer as

<h3>2.8 units to the nearest tenth</h3>

When Doris Lessing published The Golden Notebook

ValentinkaMS [17]

There was an error in A.

<h3>What is The Golden Notebook?</h3>

The Golden Notebook is a 1962 book by Doris Lessing, a British author. It investigates mental and societal breakdown, much like her two succeeding books, which Margaret Drabble referred to as Lessing's "inner space fiction" in The Oxford Companion to English Literature. In addition to an extensive investigation of communism and the Communist Party in England from the 1930s to the 1950s, the novel also examines the nascent sexual revolution and women's liberation movements. It also contains anti-war and anti-Stalinist undertones. The Golden Notebook was listed among the top 100 English-language books published since 1923 by TIME magazine in 2005. Other languages that it has been translated into include French, Polish, Italian, Swedish, Hungarian, and Hebrew.
