Question

p=a+b+c;p=41,a=11,b=12
c = ? perimeter of a triangle ?

Answer 1

it asks "perimeter of a triangle ?"

but p = 41 is given

Answer 2

so that seems a bit odd

Answer 3

anyways, it looks like they just want the value of c

p = a+b+c

41 = 11+12+c

solve for c to get c = ???

Answer 4

im confused

Answer 5

where at?

Answer 6

all of it! lol

Answer 7

do you see how I went from p = a+b+c to 41 = 11+12+c ?

Answer 8

If not, then all I did was plug in p = 41, a = 11, b = 12

Answer 9

After you plug those values in, you have to isolate c

Answer 10

what do you get when you do that?

Answer 11

18

Answer 12

correct

Answer 13

as a check,

p = a+b+c

41 = 11+12+18

41 = 41

so the solution is confirmed
