Answer:
l = 5
Step-by-step explanation:
l = 5
W = (5 × 3) -2
= 13
13 + 13 + 5 + 5 = 36
Angles are the space between intersecting lines, and they are measured in degrees or radians
The measure of angle ABC is y + x
<h3>How to determine angle ABC</h3>
The given parameters are:
ABD=y,
DBC=x,
EFH=y,
EFG=x
PQS = SQR = x
To determine the measure of angle ABC, we make use of angle ABD and angle DBC
Note that angle ABD and angle DBC have common vertices at points B and D
So, we have:
ABC = ABD + DBC
Substitute known values
ABC = y + x
Hence, the measure of angle ABC is y + x

Answer:
The lowest whole number ratio of the elements in a compound is called <u><em>the empirical formula.</em></u>
Step-by-step explanation:
A molecular formula consists of the chemical symbols of the constituent elements of a compound followed by numerical subscripts that describe the number of atoms of each element present in the molecule.
Then, the representation of the elements that form a compound and the proportion in which they are found, or the number of atoms that form a molecule is called the chemical formula.
The empirical formula is an expression that represents the simplest proportion in which atoms that form a chemical compound are present. It is then the simplest representation of a compound. Therefore, it is called the minimum formula.
In summary, the empirical formula is a formula that indicates the simplest integer ratio of all atoms in a molecule.
Finally, <u><em>the lowest whole number ratio of the elements in a compound is called the empirical formula.</em></u>
The least common factor of x and x squared is x
