<h3>What is the unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
In one acre = 18 orange trees
1 orange tree = 1/18 acre
So, for 792 orange trees = (1/18)792
= 44 acres.
Hence, 44 acres are in orange land.

Answer:
Step-by-step explanation:
f(x) = x²-8x-20
a= 1
a >0 so...
-parabola opens up
-vertex is a minumum
Minimum because parabola opens up !
Answer: x < -3
=================================
Work Shown:
The boundary line is x = -3 as this vertical line goes through -3 on the x axis. Every point on this line has an x coordinate of -3 while the y coordinate is anything you want. So two points on this boundary line are (-3,0) and (-3,1)
The boundary line being dashed or dotted tells the reader "do not include this as part of the solution set".
So our answer will not have an "or equal to" as part of the inequality sign.
The shading to the left indicates we'll have a "less than" sign
So that's why the answer is x < -3
Every point in the purple shaded region has a point with an x coordinate that is less than -3. The value of y does not matter.
Two points in this shaded region are (-6,0) and (-4,7)
Points along the boundary line are not in the solution set.
