Given segment CE and point D that lies on CE, find CD if CE = 15, CD = 30 + 3x, and ED = 25 + 2x
klasskru [66]
CD+DE=CE
(30+3x)+(25+2x)=15
55+5x=15
x=-8
CD=30-24=6

Is the HCF of a^3-8, a^4+16 and a^3+2a^2+4a just 1?<br> Please answer........
Flauer [41]
First we find the factors
a^3-8 is the differnce between 2 perfect cubes and is factored out to
(a-2)(a^2+2a+4)
the factors are (a-2) and (a^2+2a+4)

a^4+16
this is not factorable, unless you mistiped it and it was really a^4-16
the factor is 1


a^3+2a^2+4a
factor out the a
a(a^2+2a+4)
this is the most factored out form
the factors are (a) and (a^2+2a+4)


there are no common factors except 1 so 1 is the answer

Solve the simultaneous equation
Sunny_sXe [5.5K]
Here are the original equations:
2x + 2y = 14
x + 2y = 11
We immediately note that these two equations form a system. So, we can use substitution to solve the second equation for x. To do this, all that needs to be done is to subtract 2y from both sides, to get x = 11 - 2y. Next, we substitute the derived expression for x into the first equation to get 2(11-2y) + 2y = 14. We can use the distribute property to get 22 - 4y + 2y = 14. Then, we can combine like terms to get 22 - 2y = 14. After that, we subtract 22 from both sides to get -2y = -8. Finally, we divide -2 from both sides to get y = 4. 

Now that we have the value for y, we can substitute our derived value into the second equation, since it will be much faster. After doing this, we get x + 2(4) = 11. We can simplify the left side of the equation and subtract the product from both sides, which gives us x = 4. Therefore, the answer to your query is x = 4, y = 4. Hope this helps and happy Halloween!

You have 6 different colored balloons. In how many distinct ways can the balloons be ordered?
babunello [35]

Answer: a. 720

Step-by-step explanation:

       You have 6 different sticks to choose from for the first stick. Then there are 5 for the second (6 - 1 = 5), then 4 for the third (5 - 1 = 4), etc all the way to the last stick.

       Mathematically, this can be shown with 6!. In other words, 6 factorial.

                      6 * 5 * 4 * 3 * 2 * 1 = 720

      The answer to our question is:

                      a. 720
