Answer:24x+12
Step-by-step explanation:
8(3x+4)-20
24x+32-20
24x+12
<u>7</u> <u>35</u> 4x35/7= 20 lawns<u>
</u>4 x<u>
</u>
4004 + 50.50t = 300.75t
4004 = 300.75t - 50.50t
4004 = 250.25t
4004 / 250.25 = t
16 = t <=== they charge the same at 16 tons
300.75(16) = 4812 <== they cost the same
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]
