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
Make it into a simultaneous equation:
5p + 4e = 7.65
4p + 5e = 7.20
Use adding/subtracting formula
The cost of an eraser is $1.44
Answer:
The Answer Would Be C. A'(-5, -5), B'(-5, -1). C'(-2,-1).
D(5, -1)
Quick math. ;)
<span>-5/s -1/2s
.The least common denominator is 2, since 2 is divisible by 1 and by 2
The answer will be : </span><span>-5/s -1/2s = -10/2s - 1/2s = -11s/2</span>
Answer:
