Write the indicated polynomial expression:

1. The total number of students at Mathville High School can be expressed as 7x^2+8x-16. If the number of male students at Mathville High is 3x^2+14, then write the polynomial expression that would represent the number of female students.

2. An amusement park sold x^2-9x+11 adult tickets and 2x^2+4x-5 children's tickets. Write a polynomial expression that represents the total number of tickets sold.

3. A taxi traveled x^2+8x-13 miles on Monday and x^2+10 miles on Tuesday. If the total miles traveled by the taxi on Monday through Wednesday was 2x^2+20x+19, then write a polynomial expression that represents the number of miles the taxi traveled on Wednesday.
PLEASE HELP!! WILL MARK BRAINLIEST!!

1. The first expression tells the total number of students as well as the male students. This means you only have to subtract to find the female number

7x^2+8x-16-(3x^2+14); Simplify

4x^2+8x-30, if you wanted it factored then if would be this;

2(2x^2+4x-15).

2. For this one you add the polynomials.

x^2-9x+11+2x^2+4x-5; Simplify

3x^2-5x+6

3. Ok, for this one you have the number of miles traveled on Monday and Tuesday ( x^2+8x-13+(x^2+10)) and the total numbers traveled from Mon.-Wed (2x^2+20x+19). So, you first need to add Monday and Tuesday and then subtract that amount from the total of miles on Mon.-Wed.

( x^2+8x-13+(x^2+10))

=2x^2+8x-3

2x^2+20x+19-(2x^2+8x-3)

=12x+21, or if you wanted it factored;

3(4x+7)
