This is a communication question. Suppose you are given the equation P= -n2+480n- 42 000. This equation represents a concerts profit where P represents profit (in
dollars) and n represents the number of tickets sold. What must you set to 0 in order
to determine the number of tickets needed to be sold to break even?

c is the answer

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
