The length of three sides of a triangle are (x+1) cm 2xcm and 3x+1) cm its perimeter is 30cm. Find the value of x and the length of wach sides of triangle

Start by writing a formula-

30 = (x+1) + (2x) + (3x+1)

Combine like terms-

30=6x+2

Subtract 2 from both sides

28=6x

Divide both sides by 6

4.666≈x

You can then check this by plugging in 4.666 to your formula and adding to see if it works. Remember, x is roughly equal to 4.666.
