How do you simplify the expressions?

y(3 + x) + x²

y + x² + x²

i havent done algebra in a year so correct me if im wrong

1. 3y + xy + x^2

2. y +2x^2

1. 3y + xy + x^2

2. y +2x^2

Explained:

y(3 + x) + x²
3y + xy + x²

If there is a term directly outside a set of brackets, in this case y, use that term and multiply everything that is inside the brackets, therefore:

3y + xy + x²

x² is not inside the brackets and is not affected.

-

y + x² + x²
y + 2x²

Another algebra rule, "collect like terms". If you see similar bases, you may collapse them. Another way to look at any equation without numbers in front (ex. 3x or 5y, compared to a lone x), is

1y + 1x² + 1x²

Therefore you can add the two x²'s, giving you

y + 2x²

*bump* wait a few hours, I'll edit this post some while later.

Really sorry for the double post, but:

E:
(x and y are two different numbers selected from the first fifty counting numbers from 1 to 50 inclusive. what is the largest value that x + y can have? show working out.
x - y

I don't understand at all, please help :S

okay so have any of u read the book eleanor and park? I have this assignment to do where i have to pick ten of this things to describe a character in the book

math homework: draw the following trapezoids. if not possible explain why

trapezoid with 2 right angles
trapezoid with three right angles
trapezoid with 4 right angles

trapezoid with 2 right angles
trapezoid with three right angles
trapezoid with 4 right angles

1. 2 right angles

2. 3 right angles
Impossible, bc that would mean the fourth side also has to be a right angle
3. 4 right angles
Impossible, that's a square or rectangle

thank u so much!

this thread is very helpful

this is basically a thread for helping people cheat on their homework, nice job guys. i'll definitely come here once in a blue moon to get some answers!

divide the toy's measurements by 2 then multiply that by 3 because every 2 inches is 3 meters
so the answer to #1 would be 24 meters, #2 would be 15, #3 would be 6, and #4 would be 8.1

omg thank u

I'm too lazy to look this up on my own, but when you're transforming a parabola, why is it that moving the x to the left is a positive change rather than a negative change?

rationalize radical expressions with denominators
lol i dont wanna do this one

I remember this thread!

I hope this thread dies out so people can stop sucking help off of it

It's like getting tutoring from a familiar community. There's nothing wrong with it, it's not like people are cheating.
