Answer:
B is the correct answer. (X U Y)
Answer:
E
Step-by-step explanation:
You can easily solve this by rearranging the ones that look alike. 7a^2-5a^2+10a-3a=5a^2+7a
According to PEMDAS (Parenthesis, exponents, multiplication, division, addition, subtraction), we should start off with doing (14 - 8). Using simple math you can find out that the answer would be six.
Now we should do the multiplication, because that comes next in PEMDAS. Since you have found the answer in the parenthesis, you can should substitute it for the answer, in this case, it substitute it for six.
(Because you did not put an ^ before the two, I am just going to assume that it is times two.)
So now we just do 6 x 2, to get 12. After that we just to do 12 - 6, which equals six, and then add that to our other number 12, to get our answer of 18.
So the answer is 18 or eighteen.
To reach $3,900 with an interest rate of four percent on an account originally containing $1,100, it would take 32.27 years.
