Hello,
Height: y
Number of branches: B=y-3
Number of leaves on one branche:n=10B²-B
Number of leaves on the tree:
nb=n*B=(10B²-B)*B=10B^3-B²
=10(y-3)^3-(y-3)²=(y-3)²[10(y-3)-1]=(y-3)²(10y-31)
a) if y=9 then nb=(9-3)²*(10*9-31)=36*59=2124.
Answer:
9
Step-by-step explanation:
divide 36 by 4 and its nine
