The volume of a tetrahedron is 1 6 of the volume of a parallelepiped whose sides are formed using the vectors coming out of one
Irina18 [472]

Answer: The volume of the tetrahedron is 2 units.

Step-by-step explanation:

Let A = (1, 1, 1)

B = (1, 5, 5)

C = (2, 2, 1)

The volume of a tetrahedron is given as

V = (1/6)|AB, AC, AD|

Where |AB, AC, AD| is the determinant of the matrix of AB, AC, AD.

We need to determine AB, AC, and AD

Suppose A = (a1, a2, a3)

B = (b1, b2, b3)

C = ( c1, c2, c3)

AB = ( b1 - a1, b2 - a2, b3 - a3)

Similarly for AB, AC, BC, etc.

AB = (1 - 1, 5 - 1, 5 - 1)

= (0, 4, 4)

AC = (1, 0, 2)

AD = (1, 1, 0)

Volume =

(1/6) |0 4 4|

|1 0 2|

|1 1 0|

= (1/6)[0(0 - 2) - 4(0 - 2) + 4(1 - 0)

= (1/6)(0 + 8 - 4)

= (1/6)(12)

V = 12/6 = 2 units

Simplify 3/15 - 2/25
Alik [6]
Make the denominators equal by multiplying them:
\frac{18}{75}  -  \frac{6}{75}
Subtract:
\frac{12}{75}
Simplify:
\frac{4}{25}
The answer is
\frac{4}{25}
or 0.16

3x+7= x-1 does x = -4?
vaieri [72.5K]
Subtract x from both sides:
(3x - x) + 7 = (x - x) - 1

3x - x = 2x:
2x + 7 = (x - x) - 1

x - x = 0:
2x + 7 = -1

Subtract 7 from both sides:
2x + (7 - 7) = -7 - 1

7 - 7 = 0:
2x = -7 - 1

-7 - 1 = -8:
2x = -8

Divide both sides by 2:
2x / 2 = -8 / 2

2 / 2 = 1:
x = -8 / 2

The gcd (greatest common denominator) of 8 and 2 is 2:
-8 / 2 = 2(-4) / 2x1 = 2/2 x - 4 = -4

x = -4
