Answer:
49n² - 70n + 25
Step-by-step explanation:
Area of a square = s²
Where,
s = side length = 7n - 5
Area of the square = (7n - 5)²
= (7n - 5)(7n - 5)
= 7n(7n - 5) -5(7n - 5)
= 49n² - 35n - 35n + 25 (distributive property of equality)
Add like terms
Area = 49n² - 70n + 25
Step-by-step explanation:
i might be wrong sorry x
No. The value in the hundreds place represents 500, whereas the value in the tens place represents 50. The value in the hundreds place is 10 times as great as the value in the tens place.
Answer:
Having brown hair and having freckles are not necessarily independent events
Step-by-step explanation:
We are given the following information in the question:
Percentage of children having brown hairs = 46%
Percentage of people children having freckles = 25%
But it cannot be concluded that
German children of Caucasian descent are brown‑haired with freckles =

This is not always true because of the following reasons:
Brown hair and having freckles are not necessarily independent events.
We can not assume that event of a child having brown hair is independent of the event of child having freckles. The events could be dependent as well.
The above will only be true when event of a child having brown hair is independent of the event of child having freckles.
If the events are independent then,

C or d i think is the correct answer
Answer:
Perpendicular bisector for the given segment AB is shown below.
Step-by-step explanation:
Construction steps for the perpendicular bisector for the given segment AB are:
1. Open your compass more than half of the distance between end points of the given segment, i.e., A and B.
2. Place the compass on point A and mark two arc on each side of line segment AB.
3. Place the compass on point B and mark two arc on each side of line segment AB, which intersect the previous arcs.
4. Arcs meet at two points. Mark them C and D.
5. Draw the line between C and D.
The perpendicular bisector for the given segment AB is shown below.
