Sums of cubes can be factored as

So

Answer:
$308
Step-by-step explanation:
First, you have to find out how much it costs per pound, so you would divide 231 by 21. each pound of potatoes costs $11. so 11 x 28 would make it $308.
Answer:
Step-by-step explanation:
m ∠XOY = m ∠WOV
so, m XY = m WV --- (i)
{ If angle subtended by two arcs at the center are equal, then length of arc are equal}
m YZ = m ZW ------- (ii) {given}
Add (i) and (ii)
XY + YZ = WV + ZW
XZ = ZV
Hence proved.
a=c because the transitive property states so.
L = (2,2)
H = (0,3)
G = (1,5)
M = (6,7)
P = (4,8)
C = (7,0)
