(m + n + 3)(m + n + 4)
First distribute the m in the first set of parentheses to the second set of parentheses.  Do the same process with the n and the 3.
m^2 + mn + 4m + mn + n^2 + 4n + 3m +3n + 12
Combine Like terms. Final Answer:
m^2 + n^2 + 2mn + 7m + 7n + 12

Answer:

2m+2n+7

Step-by-step explanation:

Given: Two polynomial

P_1=m+n+3

P_2=m+n+4

We need to find the sum of polynomial.

Sum=P_1+P_2

\Rightarrow (m+n+3)+(m+n+4)

write like term together  

\Rightarrow m+m+n+n+3+4

Combine the like term

\Rightarrow 2m+2n+7

Hence, The sum of two polynomial is 2m+2n+7

The number of hours walked varies inversely with the speed of the walker. if it takes sam 12 hours to complete his walking goal
Effectus [21]
We let k be the proportionality constant for the relationship between number of hours, h and speed of the walker, s. 

                        h = k/s
Substituting the known values,
                        12 = k/5
                          k = 60

For the second scenario,
                          h = k/s
Substituting the calculated value for k and the given value for speed,
                          h = (60)(3 miles/hour)
                         h = 20 hours
                         h = 20 hours

Therefore, it will take 20 hours to walk with a speed of 3 miles per hour.
