C = 50P

The cost for 19 people is $950.

Step-by-step explanation:

For 1 person, C = 50

For 2 people, C = 50 × 2

For 3 people, C = 50 × 3

...

For P people, C = 50 × P = 50P

The equation is

C = 50P

For 19 people, P = 19.

C = 50 × 19

C = 950

The cost for 19 people is $950.

950

Step-by-step explanation:

C×P

cost×people

50×19

=950

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
