The required inequality is: x≤7
Step-by-step explanation:
The words have to be considered and observed properly to write an inequality.
At most means, that the value cannot exceed 7.
So,
Let x be a number
Then
A number is at most 7 will be written as:
as the value of x cannot exceed 7.
The required inequality is: x≤7

The area of the triangle can be calculated using the distance formula if the coordinates are given.
<h3>What is the triangle?</h3>The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle with coordinates on the coordinate plane.
It is required to find the area of the triangle using the coordinate points.
Here the coordinates are not given, so we are assuming the coordinates are (x1, y1), (x2, y2), (0,0)
From the distance formula:
The distance(b) between (0, 0) and (x1, y1):
The distance between (0, 0) and (x2, y2):
So the area of the triangle:
A = bh/2
Thus, the area of the triangle can be calculated using the distance formula if the coordinates are given.
