The surface area of a regular tetrahedron with edge length s is
... A = (√3)s²
For your edge length of 4 inches, the surface area is
... A = (√3)(4 in)² = 16√3 in²

Answer:
Henry will need 6 pints of red color.
All together he will need 15 pints.
Step-by-step explanation:
Henry needs 2 pints of red paint and 3 pints of yellow paint to get a specific shade of orange.
The ratio is 2:3
Now he uses 9 pints of yellow paint so we need to find the pins of red paint used to get the same orange.
Let the pints of red paint be x
We can relate this as:
Solving for x;
So, x = 6
Hence, 6 pints of red color are needed.
And all together Henry needs 
pints of paint.
Answer:
3
Step-by-step explanation:
If r=2, that means that each term in the geometric sequence is multiplied by 2.
So, if r=2, and the sixth term in the sequence is 96, then simply divide by 2 until you get to the first term.
Which is 3.
Answer:
Graph the equations
Step-by-step explanation:
x - y = 1
3x + 2y = - 12
Rewrite equations into y=mx+b form:
y = -1 + x
y = -6 - 1.5x
Graph it!
