Answer:
2x^2 + 2y^2 + 2z^2
Step-by-step explanation:
x^2+xy-yx+y^2 + y^2+yz-zy+z^2 + z^2+zx-xz+x^2
First step is to put all the same ones together
( FYI, xy and yx is the same thing, just like how
2 x 3 and 3 x 2 is the same thing) this time I'll bracket the groups to make it easier on the eyes
(x^2 +x^2) + (xy - xy) +( y^2 + y^2) + (yz - yz) +
(z^2 +z^2) + (zx - zx)
2x^2 + 2y^2 + 2z^2
All the others just cancel themselves out, for example, xy-xy
When anything minus themselves it will become 0
Answer:
<em>Functions:</em>
3. The chart with arrows
4. The graph
<em>Not Functions:</em>
1. (1,1), (2,2), (3,3), (1,4)
2. (1,17), (0,16), (0,15), (-2,17)
Step-by-step explanation:
Functions do not have repeating domains (x-coordinates).
Hope it helps!
8 3/5 - (1 1/2* 3 1/5)
= 43/5 - 24/5
= 19/5
= 3 4/5
Final answer: 3 4/5~
The surface area of square pyramid is the sum of the area of all its sides.
If l is the slant height and base is s each then surface area of pyramid is given by:
Surface area = s2+2xsx l
From the given figure in the question:
S=6 cm ,l= 8cm.
Substituting these values in surface area formula we have:
Surface area = 62+2x6x8
Surface area = 36+96
Surface area =132cm2
