weqwewe [10]

Answer:

8/7 min  = 1 \frac{1}{7}   minutes

The sides of a triangle are given as 3x, x - 1 and 3x + 1. If the perimeter [2]
sveta [45]

Answer:

The sides are 24cm, 7cm, and 25cm

Step-by-step explanation:

3x+x-1+3x+1=56 <---- First we combine like terms (the 1's cancel out)

7x/7=56/7 <--- Divide by 7 to isolate the variable

x=8 <--- Now that we've solved for x we need to plug it back into each side

3(8)=24

(8)-1=7

3(8)+1=25

24+25+7=56 <---- Make sure it all adds up to 56

Hope this helps :)
