Answer:
3x+9
Step-by-step explanation:
1(x+2) +1(x+3) +1(x+4)
<em>x+2+x+3+x+4</em>
<em>x+x+x+2+3+4</em>
<u><em>3x+9</em></u>
Answer:
Step-by-step explanation:
surface area=2×l×b+2(l+b)×h=2(lb+lh+bh)
=2(6×2+6×4+2×4)
=2(12+24+8)
=2×44
=88 square units.
For this case we have the following statement:
<em>"You have 2 meters of fabric and you cut 85% to make curtains, 50% of the rest to make the strips that hold it. How many centimeters of fabric were left?"</em>
So, we have:
2 meters ---------> 100%
x ----------------------> 85%
Where "x" represents the amount of fabric meters equivalent to 85%.
![x = \frac {85 * 2} {100}\\x = 1.7](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B85%20%2A%202%7D%20%7B100%7D%5C%5Cx%20%3D%201.7)
Thus, 1.7 meters of fabric were used to make curtains.
There are 0.3 meters of fabric left, of which half (50%) is used to make the strips that hold the curtain. That is to say:
![\frac {0.3} {2} = 0.15m](https://tex.z-dn.net/?f=%5Cfrac%20%7B0.3%7D%20%7B2%7D%20%3D%200.15m)
Thus, 0.15 meters of fabric remain.
![0.15 m * \frac {100 cm} {1 m} = 15\ centimeters.](https://tex.z-dn.net/?f=0.15%20m%20%2A%20%5Cfrac%20%7B100%20cm%7D%20%7B1%20m%7D%20%3D%2015%5C%20centimeters.)
Thus, 15 cm of fabric remain
Answer;
15 cm
The interquartile range is 10.
Explanation:
-Find the median, (which is 43).
-Then find the first and third quartiles (40 and 50).
-Subtract 50 - 40
- And the answer is 10
