The length of a rectangle is represented by the function L(x) = 6x. The width of that same rectangle is represented by the function W(x) = 4x2 − 3x + 8. Which of the following shows the area of the rectangle in terms of x?

keigh2015 · Answer

(L ⋅ W)(x) = 24x3 − 18x2 + 48x
 (L ⋅ W)(x) = 24x3 − 3x + 8
 (L + W)(x) = 4x2 + 3x + 8
 (L + W)(x) = 4x2 − 9x + 8

Which one do you believe it is?

keigh2015 · Answer

I think the first one

misssunshinexxoxo · Answer

We know the length is 6 "W(x) = 4x2 − 3x + 8"  the first is correct after plugging it in

misssunshinexxoxo · Answer

All you got to do with area is plug it in and sometimes factor; this is leading you into geometry. Get ready for it.

keigh2015 · Answer

So I multiply? This is getting me to confused

misssunshinexxoxo · Answer

Yes, length x width

ok so did i have it correct? with the first one?

misssunshinexxoxo · Answer

Solve this for the width  W(x) = 4x2 − 3x + 8; Yes you did :)
