Your job is to paint lines in a long, straight parking lot. You determine the dividing lines need to be parallel. The length of the parking lot next to the curb is 162 ft. You need to determine which angle the lines should be drawn with the curb to maximize the number of cars that can park.

a. How far apart should the lines be?
b. What angle should they each be with the curb?
c. Is the angle right, obtuse, or acute?
d. What is the measure of the angle adjacent to the angle you calculate?
e. Is the angle right, obtuse, or acute?
f. How are the two angles related?
g. How many spots will there be?

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.

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

[10 points, algebra 2-simplifying complex fractions]according to my answer key the restrictions are -1 and 4. but why not positive 1?
