#3 After t seconds, a ball tossed in the air from the
ground level reaches a
height of h feet given by
the equation
h(t) = 8t - 7
a) What is a reasonable
domain and range for
this situation?
Domain -
Range
b) How high did the ball travel?
c) How long did the ball travel?

Is δ pmr similar to δ smn ? if so, which postulate or theorem proves these two triangles are similar?

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.

I'll give brainliest if you answer right : )
