Answer:
-37
Step-by-step explanation:
It would be greatly appreciated if you gave me brainlest
One application of volume is determining the density of an object. Assume the object is made of a pure element (eg: gold). If we know the volume (v) of the object, and we know the mass (m), then we can use the formula D = m/v to figure out the density D. Knowing the volume is also handy to determine if the object can fit into a larger space or not. Another application is figuring out how much water is needed to fill up the inner space of the 3D solid (assuming it's hollow on the inside).
The surface area is handy to figure out how much material is needed to cover the outer surface. This material can be paint, paper, metal sheets, or whatever you can think of really. A good example is wrapping a present and the assumption is that there is no overlap.
- 5.5 + 3.5
the answer is -2
first you soustracte. -
- × - = +
Answer:
Option D) is correct
That is x=2 , y=-5
Step-by-step explanation:
Given that the 
To find their determinants

=-8+48
=40
Therefore 

=-76+156
=80
Therefore 

=104-304
=-200
Therefore 
To find the values of x and y:

and 
x=2 and y=-5
Option D) is correct
That is x=2 , y=-5
Answer:
the slope is 1 up and 7 left (mx part of the equation) and the 2 is where you start on the y axis. So you start at 2 on the vertical axis, and move up one and left 7, and put a point on where you land and continue.
