QUICKKK PLEASE SOLVE AND EXPLAIN WILL GIVE 50POINTS ILL REPORT YOU IF YOU JUST TAKE THEM A restaurant manager can spend at most $400 a day for operating costs and payroll. It costs $80 each day to operate the restaurant and $40 dollars a day for each employee. Use the following inequality to determine how many employees the manager can afford for the day, at most:

40x + 80 ≤ 400
a)x ≥ 8
b)x ≥ 12
c)x ≤ 8
d)x ≤ 12

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
