The first side of a triangle is 3 inches shorter than the second side, and 2 inches longer than the third side. How long is each

uysha [10]

Answer:

Since

is 8 in. shorter than the second side, we know that we'd need to add 8 to

to get the length of the second side. So the second side is

. (Think, if the first side is 2 inches and it is 8 inches shorter than the second side, the second side must be 10 inches, so this works.)

The third side is 4 times the length of the first side, so the third side is

Perimeter is the sum of the sides, so:

( x ) + ( x + 8 )+ 4 x = 6 x+ 8

We also know the perimeter is 26, so we have:

6 x + 8 =26

subtract 8:

6 x =18

divide:

x = 3 .

The three sides have length: 3, 11, and 12.

The longest side is 12 inches long.
