Answer:
6 is answer
Step-by-step explanation:
x+3=9
or, x=9-3(because we have to change sign)
therefore, x=6ans//

When taking a polynomial modulo

, you reduce its terms' coefficients modulo

, so that, in conjunction with the result above,

For completeness, the linear term's coefficient should also get reduced in the same way as the constant term, so that
Answer:
Step-by-step explanation:
d = c-b / a-n
Make b the subject
d (a - n) = c - b
-b = d (a - n) / c
Divide both sides by - 1
-b / -1 = d (a - n) / c ÷ -1
b = d (a - n) / c × 1/-1
= d(a - n) / - c
= ad - an / - c
The options given doesn't match the final answer
Answer:
3 meters
Step-by-step explanation:
We are told that ...
the radius of circle P is half the radius of circle Q.
The same relation applies to any corresponding linear measures of these circles, so we can also say ...
the diameter of circle P is half the diameter of circle Q
the diameter of circle P is half of 6 meters, so is 3 meters
Answer:
~15 meters away
Step-by-step explanation:
c^2 = a^2+b^2
c^2 = 10^2+11^2
c^2 = 100+121
c^2 = 221
c = 
c = ~15
