Solve v2 = 47.

please :)

v=± 47=±6.8557

Step-by-step explanation:

(1): "v2" was replaced by "v^2".

(2) Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: v^2-(47)=0

2x^2+5x+17

your welcome. : )

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
