Answer: x= 5


Step-by-step explanation:

distribute the -2 into the parentheses then do the same for the 3 on the other side of the plus sign then combine like terms  you end up with 6x-5=25 to undo that add the five to the 25 to get 6x=30 divide by 6 therefore you end up with x= 5

Brian has 64 flowers for a big party decoration. In addition, he is planning to buy some flower arrangements that have 18 flower
Volgvan

Answer:

The answer is 18x+64 ={the five terms it gives you} <(they might be different for everyone)

Step-by-step explanation:

I had the same question on my quiz and I used process of elimination to get the answer. According to my quiz, I'm assuming that you've had the same four answer choices that I had.

First off, the variable must be on 18, since it says 18 flowers each, which will eliminate two answer choices, another piece of evidence is that X is supposed to represent the numbers of flower arrangements.

Now we are left with two different answer choices, one of which is missing a term. This is a problem since it says that he has enough to have up to five of them. Since one of the answer choices has only four terms, it is safe to say it is incorrect.

Conclusion

This leads the answer to be 18x+64={five terms, not four}

I hope this helps, good luck on the rest of your assignment/quiz! :D

Find sin2a if sina=3/5 and a is in quadrant 2
LenKa [72]
Sin(a)= \frac{3}{5}

To find sin(2a) = 2*sin(a)*cos(a), we ned to find cos(a)

We know that,

sin²(a) + cos²(a) = 1

cos(a) = \sqrt{( 1- sin^2 a)}

cos(a) = \sqrt{1- ( \frac{3}{5} )^2} =  \sqrt{1-  \frac{9}{25}} =  \sqrt{ \frac{16}{25}} =  \frac{4}{5}

Thus, cos(a) = +- \frac{4}{5}

We know a is in second quadrant and thus cos(a) is -\frac{4}{5} because cosine is always negative in the second quadrant.

Therefore,

sin(2a) = 2*sin(a)*cos(a) = 2* \frac{3}{5} * \frac{-4}{5} =  \frac{-24}{25}
