CCSS REASONING At a Fourth of July celebration, a rocket is launched straight up
with an initial velocity of 125 feet per second. The height h of the rocket in feet
above sea level is modeled by the formula h = 125 - 167-, where t is the time in
seconds after the rocket is launched.
a. What is the height of the rocket when it returns to the ground?
b. Let h = 0 in the equation and solve for t.
C. How many seconds will it take for the rocket to return to the ground?

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.
