Answer:
![\huge\boxed{V=44cm^3}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7BV%3D44cm%5E3%7D)
Step-by-step explanation:
(look at the picture)
The formula of a volume of a rectangular prism a × b × c:
![V=abc](https://tex.z-dn.net/?f=V%3Dabc)
We have two rectangular prisms.
![1:\ 2cm\times2cm\times5cm\\2:\ 2cm\times2cm\times6cm](https://tex.z-dn.net/?f=1%3A%5C%202cm%5Ctimes2cm%5Ctimes5cm%5C%5C2%3A%5C%202cm%5Ctimes2cm%5Ctimes6cm)
Calculate the volume:
![V_1=2\cdot2\cdot5=20(cm^3)\\\\V_2=2\cdot2\cdot6=24(cm^3)](https://tex.z-dn.net/?f=V_1%3D2%5Ccdot2%5Ccdot5%3D20%28cm%5E3%29%5C%5C%5C%5CV_2%3D2%5Ccdot2%5Ccdot6%3D24%28cm%5E3%29)
The volume of the irregular figure:
![V_F=V_1+V_2\\\\V_F=20cm^3+24cm^3=44cm^3](https://tex.z-dn.net/?f=V_F%3DV_1%2BV_2%5C%5C%5C%5CV_F%3D20cm%5E3%2B24cm%5E3%3D44cm%5E3)
Answer:
-5m - 14
Step-by-step explanation:
![-8m-8+3m-6\\-5m-14](https://tex.z-dn.net/?f=-8m-8%2B3m-6%5C%5C-5m-14)
The range is the simplest measure of variation . It is the difference between the biggest and smallest random variable.
Range= maximum value - minimum value
ex. Therefore in the range of these variables: (2,4,4,7} you would do 7 minus 2
Answer:
90
Step-by-step explanation:
900 is 90 tens
Check
900/10 = 90
or....
90 * 10 = 900
Hope this helped!

Answer:
the expressions are not equivalent
Step-by-step explanation:
7(x+2y) (distribute 7 into the parentheses)
= x(7) + 2y(7)
= (7x + 14y) ≠ (14x + 14y)
hence the expressions are not equivalent
