The perimeter of the triangle shown on the right is 369 feet.
Stolb23 [73]

Answer:

^two dimentional figure with algebra^

the perimwter from triangle is:

s1 + s2 + s3

ok, enter:

s1 + s2 + s3= 369

x + (8x -5) + 2x = 369

x + 8x - 5 + 2x = 369

group according to the same variable

(x + 8x + 2x) + (-5)=369

11x + (-5)=369

11x - 5= 369

11x = 369 + 5

11x =374

x =374 : 11

x = 34

ok, subtituted:

s1= x

=34 feet

s2= 8x - 5

=8(34) - 5

=272 - 5

=267 feet

s3= 2x

=2(34)

sdas [7]

Answer:

(3, 1)

Step-by-step explanation:

plotting these points on a graph, while (3, 1) may look like it's on the line, it is the only point that would involve changing the slope of the line, so that point cannot be on the line.
