Because if the exponent is an even number, x can also be -x. For example, -4^2=4^2 but -4^3 isn't the same as 4^3

Step-by-step explanation:
Correlation
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.
Anxiety symptoms and life satisfaction are negatively correlated. As life satisfaction increases the anxiety symptoms decreases.
Thus, a moderate correlation between them can be expressed by a correlation coefficient of -0.5
Answer:
(y + 6)(4u + a)
Step-by-step explanation:
Given
4u(y + 6) + a(y + 6) ← factor out (y + 6) from each term
= (y + 6)(4u + a) ← in factored form
If all angles are right angles then they are 90°
If x is equal to -3 then 2X +7 is equal to one
IfN squared is equal to 81 then N is equal to nine
