What is the value of X to the nearest tenth? <br> Answer options: 0.3, 14.4, 3.4
Nookie1986 [14]

Answer: x=14.4

Step-by-step explanation:

The triangle shown in the figure attache is a right triangle. Therefore, you can calculate the missing side "x" as following:

tan\alpha=opposite/adjacent

Where:

\alpha=64\°\\opposite=x\\adjacent=7

When you solve for x and substitute the values shown above, you obtain the following result:

x=7*tan(64\°)\\x=14.35

x≈14.4

What is the sum of 5x^2y and (2xy^2 + x^2y)
eimsori [14]
Recognize that you must combine "like" terms.  5x^2y and x^2y are "like" terms.

Adding them together, you get 6x^2y.  

Now add 2xy^2 to 6x^2y.  These are NOT "like" terms, so you end up with 
6x^2y+2xy^2 as your final answer.  This answer is acceptable as is.  

However, you could factor out the common factors:  2xy(3x+y).
