HELP!!! Algebra!!!?

Question

hey i totally forgot how to do this and we have a test on it tomorrow and i forgot my book at school, but i wrote down the problems we are supposed to have for homework plz help! we are working with distributive property and simplifying
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)=

Answer 1

1. 16+4(x+5)=16+4x+20=36+4x
2. -11(2-2x)+4=-22+22x+4=-18+22x
3. 10-3(x-1)=10-3x+3=13x+3
4. 4+2(6y-2)+5y=4+12y-4+5y=17y
5. 2(3x-2)+3(5y-1)=6x-4+15y-3=-7+6x+15y
6. 5-(n+3)+3n=5-n-4+3n=1+2n
7. -3(6x-6)+2(9x-9)=-18x+18+18x-18=0
8. 3(d+5)-3(3-d)=3d+15-9+3d=6d+6

Answer 2

First do the multiplication. So on #1 you would mutliply 4 times X +5 and get 4X+20+16. This equals 4x + 36. Then subtract 36 from the right side and you get 4x= -36. Divide by 4 and you get
-9. X= -9. Always do the mutliplication first or division first. Then add similars properties and then solve for x.

Answer 3

1) x=-1
2)x=-21
3)x=31
4) does not solve...but can be simplified to 17y the other values cancel
5)x= 3/2(5y -1) +2
y=[2/3(x-2)-1)
6)n=7.5
7) entire equation cancels out. simplifies to 0
8)6d-6

Answer 4

For increasing cubic binomials the known formula is as follows: (a + b) ^ 3 = a^3 + 3*a^2*b^a million + 3*a^a 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)^a million + 3*x^a million*(-y^5)^2 + (-y^5)^3 Simplified: =x^3 - 3x^2*y^5 + 3x*y^10 - y^15 :D

Answer 5

Read your textbook and figure it out. I haven't had algebra in years and I can still figure these out, so you should at least get a grasp of the subject. Anyone telling you just the answers will not be helping you. Remember, solve for x by doing the opposite.

Answer 6

Just don't worry about it, more than likely you are hot cause you forgot you book because you had better things to do so don't worry about math your looks will take you far. Or sleep with your math teacher.

Answer 7

here's the answer and problem solving for #6:

5 - (n + 3) + 3n = 0
-5 -5
---------------------------
-(n + 3) + 3n = -5
- 3n - 3n
---------------------------
-(n + 3) = -5 - 3n
remove the negatives from both sides(negate eachother)
----------------------------
n + 3 = 5 + 3n
-n -n
---------------------
3 = 5 + 2n
-5 -5
-----------------
-2 = 2n
divide by two
------------------
-1 = n


hope this helps!

Answer 8

I think you should do it yourself and stop cheating here. What is the point of school if you dont learn anything? If you cheat in school you will have a crummy life! Do it yourself, you'll be better off.

Answer 9

16 + 4x + 20 =
36 + 4x =
4x = -36
x = -9
you follow?

Answer 10

what does everything equil?
