Answer:
x^3 + 2x^2 + x + 3
Step-by-step explanation:
When it says that that the polynomial is subtracted from the value x^3 - x^2+ 3x, that would mean that the answer can be computed from the following format:
(x^3 - x^2+ 3x) - (-3x^2 + 2x - 3)
Use the distributive property for the better, distributing the - to the numbers in parenthesis, to get:
(x^3-x^2+ 3x) + 3x^2 -2x + 3
Now take the parenthesis out of the first polynomial in the equation, as it isn't needed:
x^3 - x^2 + 3x + 3x^2 - 2x + 3
Rearrange and combine like values:
x^3 - x^2 + 3x^2 + 3x -2x + 3 ,
x^3 + 2x^2 + x + 3
Given:
The equation is:

To find:
The slope intercept form of the given equation.
Solution:
Slope intercept form of a line is:

Where, m is slope and b is y-intercept.
We have,

It is not in the slope intercept form.
We need to isolate variable y to get the slope intercept form.
The given equation can be rewritten as:




Therefore, the slope intercept form of the given equation is
.
We know that
[scale]=[measure in model park]/[measure in actual park]
[measure in model park]=[scale]*[measure in actual park]
scale=1.5 cm/50 m
If the distance between two trees in the park is 150 m
so
[measure in actual park]=150 m
[measure in model park]=[1.5/50]*[150]------> 4.5 cm
the answer is the option
<span>B. 4.5 cm</span>
If
2cm...................................5 m
?cm....................................18 m
the lenght of the room= (18*2)/5=7.20 cm
