Let
x--------> <span>represents the length of a single tile
L-------> t</span><span>he length of the floor
W------> the</span><span> width of the floor
A--------> </span>area of a tiled kitchen floor
<span>
we know that
A=W*L
A=</span>4x²<span> + 24x + 27
</span>so
W*L=4x² + 24x + 27---------> equation 1
L=2x+9------> equation 2
substitute equation 2 in equation 1
W*[2x+9]=4x² + 24x + 27
W=[4x² + 24x + 27]/[2x+9]
therefore
the answer is
the <span>expression that represents the width of the kitchen in terms of x is
</span>W=[4x² + 24x + 27]/[2x+9]
Answer:
see explain
Step-by-step explanation:
3 - 5
(X1, Y1) (X2, Y2)
which turns to at least for number 3
(11 - 8) / (-2 - 6) = -3 / 8 = -0.375
think you can figure out the rest.
then for #1 and 2
do the same thing, except choose any two points on the graphs.
for example you could choose (-1, 0) and (0, -2) for #1
in the equation this would be (-2 - 0) / (0 - (-1) = (-2)/1 = -2
