You can do 32 x .25 or 32/4
Answer:
37.7in
Step-by-step explanation:
Answer:
3.6
Step-by-step explanation:
2(5m-8)+3(m+2)=12+4(2m-1)
10m - 16 + 3m + 6 = 12 + 8m -4
13m - 10 = 8 + 8m
13m = 18 + 8m
5m = 18
m = 3.6
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:
B. 8 cm, 5 cm, 11 cm.
Step-by-step explanation:
The volume of a right rectangular prism is
V = l*w*h
Lets check the options given to see if they equal 440 cm^3
A. 7 cm, 9 cm, 6 cm.
440 = (7*9*6 )
440 = 378 False
B. 8 cm, 5 cm, 11 cm.
440 = (8*5*11)
440 =440 True
C. 6 cm, 12 cm, 5 cm.
440 = (6*12*5)
440 = 360 False
D. 12 cm, 2 cm, 5 cm
440 = (12*2*5)
440=120 False
