The expression is a bit invalid. You can't add variables by variables.
The area of the triangle is 14.1 square meters
<h3>How to determine the triangle area?</h3>
The side lengths are given as:
5m, 6m and 9m
Calculate the semi-perimeter (s) using
s = (5 + 6 + 9)/2
Evaluate
s = 10
The area is then calculated as:

This gives

Evaluate the products

Evaluate the exponent
Area = 14.1
Hence, the area of the triangle is 14.1 square meters

The First one (A) because it’s a straight line
1 17/20
the 1 is ur whole number....it stays ur whole number
17/20 = 0.85
so we have 1.85.....to turn it into a percent, move the decimal 2 spaces to the right = 185%
The letter A !!!!! has the solution x=6 that it the same solution
