Answer:
0
Step-by-step explanation:
The formula gives you a relation between S and n. For every n, you can perform the calculation and obtain an S.
So, for n=0 we get 0/2 (0+1) which equals 0. So (0,0) is an (n,S) pair.

Step-by-step explanation:
Represent trees with T and wreaths with W
Given


Solving (a): Cost of W
Substitute 3 + 4 * W for T in the second equation


Collect Like Terms


Divide through by 6


Hence, each wreath costs $16
Solving (b): Cost of T

Substitute 16 for W



Hence, each tree costs $67

Answer:60
Step-by-step explanation:
a=13 b=13 c=10
Perimeter of =a+b+c
perimeter of =13+13+10
Perimeter of =36
S=36 ➗ 2
S=18
Area=√s(s-a)(s-b)(s-c)
Area=√18(18-13)(18-13)(18-10)
Area=√18(5)(5)(8)
Area=√(3600)
Area of =60
