Answer:
E is the same distance from A and B. ⇒ D
Step-by-step explanation:
<em>Let us explain the meaning of perpendicular bisector</em>
If line m is the perpendicular bisector of line n, then
- line m intersect line n at the mid-point of line n
- They form 4 right angles around this mid-point
∵ Line CD is the perpendicular bisector of segment AB
∴ Line CD intersects segment AB at the mid-point of AB
∵ Line CD and segment AB intersected at point E
→ That means E ∈ CD and E ∈ AB
∴ Point E is the mid-point of line AB
∴ Point E divides line AB into 2 equal parts
→ That means point E is at the same distance from points A and B
∴ E is the same distance from A and B.
The value of expression when n = 3 is 22
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
We have to find the value of expression when n = 3
<em><u>Substitute n = 3 in given expression</u></em>
Thus the value of expression when n = 3 is 22
u = 19
Hope this helps, Good luck! (:
The greatest common factor of two numbers is, as the name suggests, the greatest integer that divides both numbers.
You number are already factored in product of primes, so it is obvious that the first number 133 = 19x7 is divisible by 1, 7, 19 and 133.
The same goes for 15 = 3x5: it is divisible by 1, 3, 5 and 15.
As you can see, there is no non-trivial divisor which is common to both number, so the answer is 1
