Octagons have 8 sides. If each side is 5 feet then the perimeter is 40 feet. You add up the sides.
Answer:
B
Step-by-step explanation:
Answer:
D: The slope is 3, and the y-intercept is 3/2
Step-by-step explanation:
-3+2y<4x
then
2y< 4x+ 3 (add both sides with 3)
y < 2x +3/2 ( divide both sides by 2 that is positif and we do not change the sens < )

Answer: The perimeter of the largest triangle = 117 units.
Step-by-step explanation:
Sides of smaller triangle = 10,20 and 15 units
Longest side = 20 units
Longest side of larger triangle = 52 units
Sides of two similar triangles are proportional.
Let k be proportionality constant.


Length of other two sides,

So sides of larger triangle = 52 units, 26 units , 39 units
Perimeter of largest triangle = 52 +26+39 = 117 units
Hence, the perimeter of the largest triangle = 117 units.
