Hi Larry
x^3 - 168 = [ 24(x-2)] / 2
x^3 - 168 = (24x - 48)/2
x^3 - 168 = 12x - 24
Subtract 12x - 24 to both sides
x^3 - 168 - (12x - 24) = 12xx - 24 - (12x - 24)
x^3 - 12x - 144 = 0
Now, factor the left sides
(x - 6)(x^2 + 6x + 24) = 0
Set factors equal to 0
x - 6 = 0 or x^2 + 6x + 24 = 0
x = 0 + 6 or x^2 + 6x + 24 - 0
x = 6
Answer : X = 6
Good luck !
The probability that the number selected is the square of a natural number will be

<h3 /><h3>What is probability?</h3>
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.
Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
P is the probability
F(E) is the favorable event
T(E)is the total event
The probability is found as;
Hence the probability that the number selected is the square of a natural number will be .

Use X1+X2 / 2, Y1+Y2 / 2
-3 + 2 / 2 , -5 + 7 / 2
-1 / 2 , 2/2
(-1/2, 1)
I think this is correct... I know you use the top formula
Use the distributive property.
1/7(105 + r) = 20
15 + (1/7)r = 20
Then subtract each side of the equation by 15.
15 + (1/7)r = 20
(1/7)r = 5
Divide both sides by 1/7.
(1/7)r = 5
r = 35
So, the answer to this question is r is equal to 35.
The next two patterns are 2,500 12,500
