Answer:
No, the following expression is not a difference of squares. Binomial can not be factored as the difference of two perfect squares. 3 is not a square.
Step-by-step explanation:
Factor
15x^2 - 25
(15x)^2(-5)^5
Divide by 3 and factor
5(3x^2-5)
"Theory:
A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression."
I put a picture to help u understand.

Answer:
a positive correlation is when both variables move in the same direction. a negative correlation is when the variables move in opposite directions. no correlation is when the variables are not statistically related
Step-by-step explanation:
negative correlation example: As you climb the mountain (increase in height) it gets colder (decrease in temperature).
zero correlation example: the amount of apple juice drunk and level of intelligence
btw you have a good example of positive correlation :) it can also be when both variables decrease
