Multiply and simplify: y(2x+3y)(2x+3y)

Answers

Answer 1

Answer: Simplifying y(2x + 3y)(2x + 3y)

Multiply (2x + 3y) * (2x + 3y) y(2x * (2x + 3y) + 3y * (2x + 3y)) y((2x * 2x + 3y * 2x) + 3y * (2x + 3y))

Reorder the terms: y((6xy + 4x2) + 3y * (2x + 3y)) y((6xy + 4x2) + 3y * (2x + 3y)) y(6xy + 4x2 + (2x * 3y + 3y * 3y)) y(6xy + 4x2 + (6xy + 9y2))

Reorder the terms: y(6xy + 6xy + 4x2 + 9y2)

Combine like terms: 6xy + 6xy = 12xy y(12xy + 4x2 + 9y2) (12xy * y + 4x2 * y + 9y2 * y) (12xy2 + 4x2y + 9y3)

Answer 2

Answer: 2xy+3y^2*2xy+3y^2
3y^2 * 3y^2

Find the distance between each pair of points (1,2), (-2,2)

Answers

Hi!

So let's imagine a coordinate plane in our head. Imagine where these points are. (1,2) is in quadrant I. (-2,2) is in quadrant II.
They have the same y values, so we just need to know the distance between the x values. We can find that by subtracting.

1-(-2)=3

The distance between (1,2) and (-2,2) is 3.

Hope this helps! :)

On a coordinate plane, 1,2 and -2,2 would be 3 units apart.

What is the value of x in the problem -1\2x + 2=3

Answers

-1/2x + 2 = 3
(move the 2 to the other side of the equal sign, change the sign)
-1/2x = 3 - 2
-1/2x = 1
(swap them to make x positive)
-1 = 1/2x
-1 = 0.5x
(divide both sides by 0.5 to have x alone)
-2 = x

Therefore, x = -2.

It is -2. X= -2 (I really need to answer more questions to ask more)
