Answer:
x = 12/5
Step-by-step explanation:
take the square of both sides
(x^2+49) = (x+5)^2
x^2 + 49 = (x+5) (x+5)
x^2+49= x^2 + 10x + 25
10x + 25 = 49
10x = 24
x = 12/5
Answer:
(m º n)(x) = x -2
Step-by-step explanation:
Here, in the given expression:
m(x)= x+1 and n(x) = x - 3
To find : (m º n)(x)
Now, solving for (m º n)(x)
(m º n)(x) = m (n (x)) = m (x-3)
also, m (x-3) = (x -3) + 1 = x -2
So, (m º n)(x) = x -2
