HELP. ONLY ANSWER QUESTION 4. THANKS

Answer:
A. x+30
B. x+35
Step-by-step explanation:
A. Daniel
Since "Daniel is 30 cm taller than Katie" and "Katie's height is x cm", the expression will be x+30
B. Juli (sorry I can't type the full name due to Brainly system)
Since "Juli is 5 cm taller than Daniel" and Daniel is (x+30) cm, the expression will be (x+30)+5=x+35
