The lemght could be 15 because a triangle has two long sides and one short one and the two are equivalent
Alright...simple...showing all steps.. ;)
You have the equations...
2x+y=7
and
3x+5y=14
To be able to even solve for any of the variables...multiply the equations by...2...and..3...
2x+y=7----*3--> 6x+3y=21
and
3x+5y=14-----*2--->6x+10y=28
Thus,
6x+3y=21
-
6x+10y=28
=========
-7y=-7
y=1
Now, plug y back into any of the original equations....we'll use 2x+y=7 in this case....
2x+(1)=7
2x+1=7
-1 -1
2x=6
x=3
Thus, the point of intersection for these two equations is (3,1)
- i =

- Product rule of radicals: √ab = √a x √b
Firstly, factor out i: 
Next, apply the product rule of radicals here as such:

<u>Your answer is 5i√2, or the second option.</u>
Answer:
8.69 inches
Step-by-step explanation:
4.5C=0.72R
V=πr^2 h
/3
V=π0.72^2 16
/3
V=8.69 Inches
I apologize for the hard to understand step-by-step but the way that the equation is set up is impossible to type out under the limitation. If you have any questions about it, just ask.
