Please help!<br>what polynomial must be added to <br>−5x^3 + 4x − 3 so that the sum is x^2 − x − 1?

lakkis [162]

<h3><u>Solution:- </u></h3>

Let the number to be added be A

Now,

$\begin{gathered}\implies\quad \sf −5x^3 + 4x − 3 + A = x^2 − x − 1 \\\end{gathered}$

Transposing (−5x³+ 4x − 3 ) to other side-

$\begin{gathered}\\\implies\quad \sf A = x^2 − x − 1 -( −5x^3 + 4x − 3) \\\end{gathered}$

Remember if there is a -ve sign before a bracket the signs of whole of the terms changes on opening bracket

$\begin{gathered}\\\implies\quad \sf A = x^2 − x − 1 + 5x^3 - 4x + 3\\\end{gathered}$

Putting like terms together -

$\begin{gathered}\\\implies\quad \sf A = 5x^3 +x^2 - x -4x +3 -1 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf A = 5x^3 +x^2 -5x +2 \\\end{gathered}$

$\longrightarrow$ Therefore, 5x³+x²-5x +2 should be added to −5x³+ 4x − 3 to get x²− x − 1

There were 220 people who voted at the 6th grade meeting. Sixty percent of the voters are in favor of changing the school mascot

Bogdan [553]

To find how many people 60% is you need to do 0.60 × 220 = 132

Now you know that 60% of 220 is 132.

Then subtract 132 from 220

220 - 132 = 88

The answer is 88
