Answer:
(D) y³ - 8y² +8y +5
Step-by-step explanation:
y³ - 6y²+ 5y - (2y²- 3y - 5 ) = y³ - 6y² + 5y - 2y² + 3y +5 = y³ - 8y² +8y +5
Magnitude = sqrt (4^2 + 4^2 + 1^2) = sqrt 33 Answer
Answer:1.41666666667 or to simplify, 1.416 but the 6 is repeating so draw a bar over the 6.
Step-by-step explanation:
<h3> </h3>
The simplified form of the expression is given as 83x/56 -(97/105)
<h3>Finding the value of unknown variables</h3>
Alphabets are usually represented as unknown variables in a equation or expression.
Given the following expression shown below
6/7 x -2/3 + 3/5 + 5/8 x -6/7
Collect the like terms to have;
6/7 x+ 5/8 x -2/3 + 3/5 -6/7
Simplify
48x+35x/56 - (70-63 + 90)/105
The final expression will be given as;
83x/56 -(97/105)
Hence the simplified form of the expression is given as 83x/56 -(97/105)
