Her calculation should look like
(8+18)x3^4
26x3^4
26x81
2106
her calculations on step 2 were incorrect because 3 to the 4th power is 81
This is a TERRIBLE answer but theirs math websites that give detailed steps.
Question 1:
For this case we have the following expression:
We have to:
Rewriting:
We take common factor "-" in the denominator:
ANswer:
Question 2:
For this case we must simplify the following expression:
We eliminate parentheses keeping in mind that:
We add similar terms:
Answer:
A line can be labeled with two points on the line (e.g. ↔BC) or by just a letter, generally less than (for example, line m ).
- There really are 2 endpoints in a line segment.
- The endpoints and all the points in them have included the length of a sector, but not a line can be measured.
- It shows structures as a linear character string.
- They are commonly employed in chemicals as computers can readily handle linear data strings.
The wrong choice can be defined as follows:
- In option B, it is wrong because (segment bar) is a Line Segment.
- In option C, it is wrong because (→ or ←) is a Ray.
- In option D, it is wrong because it is a Point.
Therefore the final answer is "Option a".
