Answer:
5 and 29
Explanation:
If k= -2, l = 3, m = 4.
Then to solve
k + l + m and K^2 + l^2 + m^2 , we have to substitute the value of k, l and m with the respective values.
So for k + l + m :
k + l + m = -2 + 3 + 4 = -2 + 7 = 5
And for K^2 + l^2 + m^2:
K^2 + l^2 + m^2 = -2^2 + 3^2 + 4^2 = 4 + 9 + 16 = 29
Hope this helps
