Answer:
Density of material would be 4.09 
units is 
Step-by-step explanation:
Given: The mass of a material is 45 grams and the volume of the material is 11 cubic centimeter
Density is defined as mass per unit volume.
It is given by:
where p is the density , m is the mass and V is the volume of the material respectively.
Here, Density is expressed in grams per centimeter cubed (g/cubic cm)
Here, m = 45 g , V = 11 cubic cm
We get;
= 4.09 
therefore, density of a material would be, 
and its units is 
Answer: 
Step-by-step explanation:
Given : Two opposite sides of a rectangle are each of length x.
Let the other adjacent side be y.
The perimeter of the rectangle is 12 units.
Perimeter of rectangle is given by :-

The area of rectangle is given by :-

Hence, the area as a function x = 
The answer is 16 I think because 2*2=4*5=20-4=16 so I think 16 is the right answer
I'm pretty sure it would have to be 155. Considering a flat line has an angle of 180 and if you subtract 180 from 25 you get 155.
