Given m varies directly with n and m = 6 when n = 5. what is the value of n when m = 12?
1 answer:
Answer:
n = 10
Step-by-step explanation:
given m varies directly as n then the equation relating them is
m = kn ← k is the constant of variation
to find k use the condition m = 6 when n = 5
6 = 5k ( divide both sides by 5 )
k = = 1.2
m = 1.2n ← equation of variation
when m = 12 , then
12 = 1.2n ( divide both sides by 1.2 )
10 = n

Answer:
The answer to your question is: 83 + 6
Step-by-step explanation:
This is a square of a binomial.
(2 + 3
1.- Square of the first term
( 2 = 4(5) = 20
2.- Twice the product of the two terms
(2)(2(3
= 6
3.- Square of the second term
(3 = 9(7) = 63
4.- Write the solution
20 + 6 + 63
83 + 6
