<span>The sum of 5 times a number and -2, added to nine times a number.
.
Looking at the first part:
The sum of '5 times a number' and '-2'
we get
5x + (-2)
or
5x - 2
.
The above is then "added to nine times a number" to get:
5x - 2 + 9x
Combining x's we get:
14x - 2

<span>Take it piece by piece:
5 times a number, rewrite as 5x
plus -2, nothing to rewrite there, that's already simplified,
added to nine times a number, rewrite as 9x.
Now, rewrite as an equation:
5x-2+9x = (See, it already looks better!)
Now combine like terms:
5x + 9x -2= 14x - 2</span></span>
Answer:
y = 
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis.
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
Here the line passes through (0,
) with y- coordinate
, thus
y =
← equation of line
Answer:
D
Step-by-step explanation:
The area of a rectangle is given by the formula:

So, we are given that the area is:

And the width is:

And we want to find the length. To do so, first substitute the expressions into the equation:

Thus, to find the length, divide by (x²+3):

So, factor the numerator:

From the first two terms, factor out a x^2.
From the third and fourth terms, factor out a 3:

Combine:

Putting this back:

Cancel:

And that's our answer :)
I believe it would be D.
