Today when i was at school we were assigned algebra homework and so i wrote the problems down on a piece of paper, but i left the book at school and now i don't know how to do them! we are learning about the distributive property and simplifying. these are the problems.
1. 16+4(x+5)
2. -11(2-2x)+4
3. 10-3(x-1)
4. 4+2(6y-2)+5y
5. 2(3x-2)+3(5y-1)
6. 5-(n+3)+3n
7. -3(6x-6)+2(9x-9)
8. 3(d+5)-3(3-d)
plz help!

1. 16 + 4( x + 5) = 16 + 4x +20 =4x + 36
2. -11( 2 - 2x) + 4 = -22 + 22x +4 =22x - 18
3. 10 - 3(x - 1) = 10 - 3x + 3 = -3x + 13
4. 4 + 2(6y - 2) + 5y = 4 + 12y - 4 +5y = 17y
5. 2(3x - 2) + 3(5y - 1)=6x - 4 + 15y - 3 = 6x +15y - 7
6. 5 - (n + 3) + 3n = 5 - n -3 +3n = 2n + 2
7. 0
8. 6( d + 1), or 6d + 6

1. 16 + 4x + 20 = 4x + 36
2. -22 + 22x + 4 = 22x - 18
3. 10 - 3x + 3 = 3x - 13
4. 4 + 12y - 4 + 5y = 17y
5. 6x - 4 + 15y - 3 = 6x + 15y = 7
6. 5 - n - 3 + 3n = 2n + 2
7. -18x + 18 + 18x - 18 = 0
8. 3d + 15 - 9 + 3d = 6d + 6

1) 16+4x+20 so simplify these equations example: 4x+36 you can do the rest
2)-22+22x+4
3)10-3x+3
4)4+12y-4+5y
5)6x-4+15y-3
6)5-n+3+3n
7)-18x+18+18x-18
8)3d+15-9+3d

for instance #1 - leave the 16 there cause you cant do anything with it, distribute 4(x+5) by multiplying giving you 4*x=4x, 4*5=20. now add the 20 and the 16 because they are alike terms and you end up with 36. no more alike terms so the final answer is 4x+36 and tada! now do the rest. dont forget to look out for youre negetive and positve signs. if you need any more help post back.

I'll show you #8 for example and you can try working on the rest.
=3d + 3*5 - 3*3 - 3*-d
=3d + 15 - 9 + 3d
= 6d + 6
Hope this is help you remember distributive property!

I'll help you with the first one to show you how to do it.
First, the distributive property is multiplying the number outside of the parentheses with the "stuff" inside of them. You have to take the number outside of them (4), and multiply it with EVERYTHING inside of them ((x+5)), in order to get rid of the parentheses. So...
4(x+5) is 4 X x + 4 X 5
4x + 20
now you have to add 16, so it's.... 4x + 36

For increasing cubic binomials the final formulation is as follows: (a + b) ^ 3 = a^3 + 3*a^2*b^one million + 3*a^one million*b^2 + b^3 on your case, a is x and b is -y^5 So (x - y^5)^3 = x^3 + 3*x^2*(-y^5)^one million + 3*x^one million*(-y^5)^2 + (-y^5)^3 Simplified: =x^3 - 3x^2*y^5 + 3x*y^10 - y^15 :D

1. 16 + (4x + 20)
x = -5
2. (-22+22x)+4
x = 1.2 (repeating)
3. 10-(3x-3)
x = 1
4. 4 + (12y-4) +5y
y = 0
5. (6x - 4)+(15y-3)
6. (I think you may have typed this one wrong)
7. (-18x+18)+(18x-18)
8. (3d + 15) - (9 - 3d)

well i will just help u with some.
ok so yo uwould distibute the 4.
16+4x+20(since 4*5=20)
sp it would be
36+4x
remember combine like terms
7. -18x+18+18x-18
and combine like terms
