Answer:
16x^4 - 8x^2 y^2+y^4
Step-by-step explanation:
G=67/9 or in decimal form g=7.4
Answer:
50 cm^2
Step-by-step explanation:
The volume of a square pyramid can be found using:
v= 1/3 bh
Where b is the area of the base, and h is the height
First, we have to find the area of the base
a=l*w
In a square, all sides are equal, so we know the length and the width are both 5
a=5*5
a=25
Now, we can substitute 25 in for b, and 6 in for h
v=1/3bh
v=1/3(25*6)
v=1/3(150)
v=50
Volume uses units cubed, and in this case our units are centimeters
The volume is 50 cm^3
Answer:
2sqrt3
Step-by-step explanation:
Since this seems to be a 45, 45, 90 triangle, x and y are the same.
The hypoteneuse is always the side lengths *sqrt2
We divide the hypoteneuse by sqrt 2 and get sqrt12
sqrt12 simplified is 2sqrt3
Answer:
| 10 -10 1 |
| 1 -2 -4 |
| -8 13 -24|
Step-by-step explanation:
First multiply each element in matrix A, this gives:
| -6 - 2 -3 |
| 1 -6 -4 |
| -4 5 0 |
Now we multiply each element in matrix B by 4, this gives:
| -16 8 -4 |
| 0 -4 0 |
| 4 -8 24 |
Finally subtract this from the first matrix ( subtracting element by element) gives:
| 10 -10 1 |
| 1 -2 -4|
| -8 13- 24|
