What is the perimeter of a triangle with the given side lengths?

s1 = x – 3 ft
s2 = x + 2 ft
s3 = x + 4 ft

P = x + ft

Question

What is the perimeter of a triangle with the given side lengths?

s1 = x – 3 ft
s2 = x + 2 ft
s3 = x + 4 ft
 
P =   x +    ft

bibby · Answer

the perimeter is the summation of all the sides.
$s_1+s_2+s_3=?$

camerondoherty · Answer

The perimeter is the sum of all the sides, correct?
So just add the sides together
$$p =(x-3)+(x+2)+(x+4)$$
The solution is the perimeter, which is the sum of all sides

bibby · Answer

$s_1=x-3$
for example, $s_1+3=x-3+3=x$

so what is the answer

camerondoherty · Answer

Solve the equation I gave you first, and you'll get it

anonymous · Answer

9x

camerondoherty · Answer

Are you sure that comes out to 9x?

Or did you just take a guess?

*cough*

bibby · Answer

hmm

jdoe0001 · Answer

perimeter = $s_1+s_2+s_3$   so add them up as camerondoherty  suggested

jdoe0001 · Answer

think about it
why did you teacher give you the answer sheet along with the exercises?
if he/she just wanted you to transcribe them over, he/she would have handed out the answer sheet as well

but that defeats the idea behind doing the exercise at all
