Answer:
f(x) + g(x) = x^2 + 4x + 35
Step-by-step explanation:
Add like terms from f(x) and g(x):
f(x) + g(x) = x^2 + 3x + 28 + x + 7, or
f(x) + g(x) = x^2 + 4x + 35

Answer:
0.4 , 0.1
Step-by-step explanation:
Let number of boys be = b , number of girls = b + 4 . As total students = 20 b + b + 4 = 20 → 2b + 4 = 20 → 2b = 20 - 4 = 16 → b = 16 / 2 = 8 (boys) , so girls = 12
Prob (a random first child is a boy) = boys / total students = 8 c 1 / 20 c1, or = 8 / 20 = 0.4
Prob ( a 'Tina' out of two Tina is the last) = 2 c 1 / 20 c 1 , or = 2 / 20 = 0.1
5/6 all you do is divide by 5
