(x-y)(x^2+xy+y^2)

The first parentheses contain the cubed root of both the terms so x and y respectively. second parentheses follows the formula (a^2 + ab + b^2)
x corresponds to a and y corresponds to b. The signs are what change depending on what the original equation is. Since the original is a subtraction then the signs are -/+/+. you can remember it using the acronym SOAP. (S = same, O = opposite, AP = always positive) So the first sign is x - y (same as subtraction from original), the second and third are x^2 + xy + y^2 (opposite is a plus, and the last sign is always a positive.

How does the order of operations relate to solving multi-step equations? Use examples of solving an equation, and then evaluatin

givi [52]

The order of operations helps keep answers for multi-step equations similar. If the proper order of operations are not followed, then answers may vary. To show an example:

4 / 2 - 1

The proper order of operations would be:

Divide first, before subtracting
4 / 2 - 1
2 - 1
1

But if subtracting was done before dividing:

4 / 2 - 1
4 / 1
4

So not following the proper order would yield different and erroneous answers.

What is the exact circumference of a circle with a radius of 12 inches?

Anestetic [448]

We can get the circumference of any circle in terms of the radius with this formula. C = 2 $\pi$ r.

Where r is the radius of the circle.

And we will use 3.14 for $\pi$ .

Plug in all the values.

C = 2 * 3.14 * 2

C = 12.56

So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.

Answer:

3.75 L

Step-by-step explanation:

3 liters / 36 m^2 = x liters / 9 x 5 m^2

3 liters / 36 m^2 = x liters / 45 m^2

(45)(3) = (x)(36)

(135) = (x)(36)
