-4y = 8x
Divide both sides by -4
y = -2x
This is in the form of y = kx, where k is the constant of variation.
y = kx is the direct
That means, k = -2.
The constant of variation is B. -2.
The correct answer is option 4: 
Step-by-step explanation:
Given expression is:

The associative property states that for any three terms that are being multiplied, different order of multiplication (i.e. which two terms are multiplied first) will give the same answer.
Let a,b and c be the three terms
then

So applying the associative property on given expression

Hence,
The correct answer is option 4:

Step-by-step explanation:
there 5^(n+1) + 5^(n+2) = 5^n x 5^1 + 5^n x 5^2 breaking them as x^(a+b) = x^a x x^b
then taking common 5^n from both terms
Answer: it is A that right
The length of the square pool is 8. 49cm
<h3>How to determine the area</h3>
Note that the formula for finding the area of a square is given as;
Area = length^2
We have
Area = 72 m²
Substitute into the formula
I^2 = 72
Find the square root of both sides
I= √72
I = 8. 49cm
The length of the square pool given as I is 8. 49cm
Thus, the length of the square pool is 8. 49cm
