Answer:

Step-by-step explanation:
We want to find the lateral surface area of the cube.
The lateral surface area of a cube is given as:

where a = length of side of the cube
Therefore, given that the length of the side of the cube is 2.5 inches, the area you need to paint is:

Unlike bony fish, sharks do not have gas-filled swim bladders for buoyancy. Instead, sharks rely on a large liver filled with oil that contains squalene, and their cartilage, which is about half the normal density of bone.
It will have 2 solutions! this is because a negative and a negative cancel each other out and will make a positive under the radical.
Answer:
43091.3 or 43181.81(81 repeated)
Step-by-step explanation:
There are two answers because it depends on the method you use. You can get the second answer by plugging 95 into the equation gram*0.0022=pound or gram=(pound/0.0022). When you insert the 95, you get 43181.81(81 repeated).You can find the first answer by just looking it up on the conversion chart on google.
Answer:
(-2.2, -1.6), (3, 1)
Step-by-step explanation:
You don't have to go far to find the equations. They are right there in your problem statement. Perhaps you want to find the solutions to the equations.
Use the first equation to write an expression for x, then substitute that into the second equation:
x = 2y +1
y^2 -3(2y+1)(y) +8 = 0
-5y^2 -3y +8 = 0
-(5y +8)(y -1) = 0
y = -8/5 or y = 1
The corresponding values of x are ...
x = 2(-8/5)+1 = -11/5
x = 2(1) +1 = 3
The solutions are (x, y) = (-2.2, -1.6) and (3, 1).
