Rasek [7]

Answer:

50cm

Step-by-step explanation:

If the sides are consecutive odd integers,

Let the smallest side=y

The other sides are y+2 and y+4

The perimeter=144cm

y+y+2+y+4=144

3y+6=144

3y=144-6

3y=138

y=138/3=46cm

Therefore, the largest side of the triangle:

y+4=46+4=50cm

Therefore, the largest side of the triangle is 50cm

The mean of four consecutive even numbers is 15. The greatest of these numbers is a1. The least of these numbers is a2.
skad [1K]
X + (x + 2) + ( x + 4) + (x + 6)
-----------------------------------     = 15
                   4

4x + 12
---------    = 15
    4

Multiply by 4 on both sides

4x + 12 = 60
subtract 12 from both sides
4x = 48
divide by 4 on each side
x = 12
x + 2 = 14
x + 4 = 16
x + 6 = 18
