18x can also be expressed as:
= 2x * (4+5)
= 2x * 9
= 18x
ANSWER: 2x * (4 + 5)
Hope this helps! :)
Answer:
m = 72.9 grams
Step-by-step explanation:
Given that,
The density of a cube, d = 2.7 g/mL
Side of the cube, l = 3 cm
The volume of the cube is :
![V=l^3\\\\V=(3)^3\ cm^3\\\\V=27\ cm^3](https://tex.z-dn.net/?f=V%3Dl%5E3%5C%5C%5C%5CV%3D%283%29%5E3%5C%20cm%5E3%5C%5C%5C%5CV%3D27%5C%20cm%5E3)
Since, 1 mL = 1 cm³
Mass per unit volume is equal to the density of an object.
![m=d\times V\\\\m=2.7\ g/mL\times 27\ mL\\\\m=72.9\ g](https://tex.z-dn.net/?f=m%3Dd%5Ctimes%20V%5C%5C%5C%5Cm%3D2.7%5C%20g%2FmL%5Ctimes%2027%5C%20mL%5C%5C%5C%5Cm%3D72.9%5C%20g)
So, the mass of the cube is 72.9 grams.
