Answer:
<h2>C . 7 units</h2>Step-by-step explanation:
The question is lacking appropriate diagram. Find the diagram to the question attached.
From the diagram, it can be seen that AD = AB+BC+CD
Given the following
AD = 23units
AB = 4units
CD = 12units
To get C=BC, we will substitute the given segments into the expression above as shown;
23 = 4+BC+12
23 = BC + 4 + 12
23 = BC+16
Subtract 16 from both sides
23-16 = BC+16-16
7 = BC
<em></em>
<em>Hence the length of segment BC is 7units.</em>
Answer:
is the greatest common factor of the polynomial.
Step-by-step explanation:
Given:
The polynomial is
In order to determine the greatest common factor of all the terms, we find the greatest common factor of the coefficients separately and greatest common factor of the variables separately.
So, factors of 12 = 1, 2, <u>3</u>, 4, 6, 12
Factors of 6 = 1, 2, <u>3</u>, 6
Factors of 9 = 1, <u>3</u>, 9
Therefore, the greatest common factor among 12, 6, and 9 is 3.
Now, factors of =
Factors of =
Factors of =
Therefore, the greatest common factor among is
.
Hence, the greatest common factor of all the terms of the polynomial is
