Answer:
X^2 -5x -36
Step-by-step explanation:
formula of an area of a rectangle: ab
a-length
b-width
(x+4)*(x-9) = x^2 -5x -36
Answer:
The slope of the new road is 0.
Step-by-step explanation:
- the slope of d street line is tan(90)
[if the angle made by a line with x axis is then, the slope of that line will be tan() ]
- here, the angle made by the d street line with x axis is 90 degrees.
- if a road is to be built which is perpendicular to d street , it should make 0 degrees i.e, it should be parallel to x axis .
- so, the slope of new road will be tan(0) = 0
You can find the approximate value of h in this the same way you could with an algebraic expression.
h - 3 < 5
+3
h < 8
I think this is the answer to your question And also the solution
