The answer would be Xx3+1 the x is ment to be the multiply sigh
Answer:
I think she works 10 hours and 30 minutes
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:
x = 6, y = -5.
Step-by-step explanation:
6x + 8y = -4
-6x - 10y = 14 Adding will eliminate the terms in x:
0 - 2y = 10
y = 10/-2 = -5,
Plug this into the second equation:
-6x - 10(-5) = 14
-6x = 14 - 50 = -36
x = -36/-6
x = 6.
