A rectangle and a square have the same area. The width of the rectangle is 2 in less than the side of the square and the length
lina2011 [118]
The area of a rectangle is A=LW, the area of a square is A=S^2.

W=S-2 and L=2S-3

And we are told that the areas of each figure are the same.

S^2=LW, using L and W found above we have:

S^2=(2S-3)(S-2)  perform indicated multiplication on right side

S^2=2S^2-4S-3S+6  combine like terms on right side

S^2=2S^2-7S+6  subtract S^2 from both sides

S^2-7S+6=0  factor:

S^2-S-6S+6=0

S(S-1)-6(S-1)=0

(S-6)(S-1)=0, since W=S-2, and W>0, S>2 so:

S=6 is the only valid value for S.  Now we can find the dimensions of the rectangle...

W=S-2 and L=2S-3  given that S=6 in

W=4 in and L=9 in

So the width of the rectangle is 4 inches and the length of the rectangle is 9 inches.

Math question I need help with
muminat
Let's you and me discuss a few things that you already know:

-- What's a y-intercept ?
The y-intercept on a graph is the place where it crosses the y-axis.

-- That's the value of 'x' at the y-intercept ?
The y-intercept is on the y-axis, so 'x' is zero there.

-- Good !  So how would you find the y-intercept of a function ?
You say that  x=0  and look at what 'y' is.

-- Very nice.  What's the function in this question ?
The function is

             f(x)  [or 'y']  =  x⁴ + 4x³ - 12x² -32x + 64   .

--  Excellent.   What's the value oif that function  (or 'y')  when  x=0  ?   

       It's just  64 .

-- Beautiful.
   Are there any answer choices that cross the y-axis at  64 ?
   How many are there ?

   There's only one.
   It's the upper one on the right hand side.
