Answer: zero of the zero polynomial is additive identity where all the coefficients including constant are zero.
hope you understand. Pls make me in brainliest
Step-by-step explanation:
Answer:
D = n/5 - m^2
Step-by-step explanation:
work:
n = 5(m^2 + D)
distribute the 5
n = 5m^2 + 5D
move the 5 to the other side by subtracting from both sides
n - 5m^2 = 5D
Divide both sides by 5 to isolate D
n/5 -m^2 = D
use reflexive property to get the answer on the left side
D = n/5 - m^2
Answer:
30m
Step-by-step explanation:
A=πr²
225π=πr²
225=r²
r=√225
r=15
d=2r
d=2×15
=30m
It would be 6824 because 6825 would be 6830 and 6824 is the largest number that rounds down to 6820
