Step-by-step explanation:
let score in fourth test=x
88+98+79+x=80×4
265+x=320
x=320-265=55
<u>Answer:</u>
<h3>(

) x (

) </h3>
<u>Step-by-step explanation:</u>
To find the area of a rectangle, we have to multiply the length with the width.
In the question, the given length is 'x' and the width given is 'x +7'
So, the area would be
(
) x (
)
The area = 
So, the equation to find the area of such a rectangle would be:-
(
) x (
)

Answer:
The required factors are: x, (x + 6) and (x - 3).
Step-by-step explanation:
As per the question,
The given polynomial is:

Now,
BY factorization, we get


By splitting the mid-term, that is split 3x like:
3x = 6x - 3x
Therefore,

Now on further solving by taking common factor out, we get
![=x[x(x+6)-3(x+6)]](https://tex.z-dn.net/?f=%3Dx%5Bx%28x%2B6%29-3%28x%2B6%29%5D)

Therefore, the given second polynomial (x - 4), is not a factor of given polynomial
.
Hence, the given polynomial has three factor x, (x + 6) and (x - 3).
