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.

A 1st degree polynomial function whose graph intercepts the y-axis at 8.
asambeis [7]

Your answer can be anything in the form y = mx+8 where you replace m with any real number.

You start with y = mx+b, and then replace the b with the y intercept 8.

The y intercept is where the polynomial crosses the y axis.

The value of m does not matter. So you could have y = 2x+8 or y = 3x+8 for instance. Replace m with whatever your favorite number is.
