√3 → irrational
-1/10 → rational
0 → rational
√2 → irrational
4x10=40
1/2 x 3 x 6= 9
9x40=360
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:
(q + 4) + (d - 3) + n
Step-by-step explanation:
You have to add all of them.
You have to add q, d, and n.
so q + d + n
and then you add four more q's so
(q + 4) + d + n
and then you lost 3 dimes so
(q + 4) + (d - 3) + n
and nothing happened to n so that is the answer.
Answer:
The answer is A.
Step-by-step explanation:
The angles add up to be 180°, which makes a supplementary relationship.
