Answer: 3
Step-by-step explanation:
232 − 172 = 529 − 289 = 240
232 − 172 = (23 + 17)(23 − 17) = (40)(6) = 240
232 − 172 = (23 − 17)2 = (6)2 = 36
The difference of perfect square is 240 is correct.
When a binomial is composed of two perfect squaresseparated by a subtraction symbol,
A certain method called the difference of perfectsquares is as follows,
The difference of perfect squares method can be done by multiplying the sum and difference of the two square roots. This is shown below:
Therefor the difference of perfect square is 240 is correct.

Answer:
Common ratio =
Step-by-step explanation:
A sequence that progresses geometrically has the first term as 12.
Each number is the previous number divided by 2.
so the sequence will be 12, 6, 3, 1.5...........
Explicit formula of a geometric sequence is given by
Where = nth term of the sequence
a = first term
r = common ratio
and n = number of term
In this sequence common ratio =
=
=
Therefore, common ratio will be

The formula of a distance between two points:
We have two points A(-5, 2) and B(-5, 8). Substitute:
d is a diameter of a circle because d = 2r = 2(3).
The center of a circle is in midpoint of AB.
The formula of a midpoint:
Substitute:
Answer: (-5, 5).
Step-by-step explanation:
Point A = (-1, -3).
Midway of AB = (-3, 2).
Let Point B = (x, y).
Then (-1, -3) - (-3, 2) = (-3, 2) - (x, y).
=> (2, -5) = (-3-x, 2-y).
We have -3 - x = 2 and 2 - y = -5.
So x = -5 and y = 7.
Hence, point B = (-5, 7).
