1. If A=lw and you know A=200ft then find what l and/or w are:

"the"lengthof the gardenis1 foot lessthanthree timesthewidth

l=(3w-1)

so now you know A and L (in terms of w). Now you just combine the equation and solve for w using A=(l)w. Then you use the width you just found and solve for length and your done.

2. Is the question:

Regardless of your current equation, X intercepts are when the function crosses the X axis which means y=0 at those points. Solve the equation accordingly.

example find the x intercepts of

just solve for:

which means thatAnd

then solve the equations. So the x intercepts are x=2 bc when x=2 y=0andx=-2 bc when x=-2 y also equals zero
