If the sides are proportional you can use the formula:

3x + 4x + 5x = 240 and solve for x.

which is:  12x = 240
x = 20

The longest side is 5x, so the longest side is 100.

Solve the equation 3(x - 7) = 42
Effectus [21]

Answer:

x=21.

Step-by-step explanation:

First you distribute 3 to the parenthesis. You should get 3x-21=42 at this point. Then you add 21 to 42 to get 63. Here you should be at 3x=63. Divide 63 by 3 to get x=3
