Answer:
Step-by-step explanation:
f(x) = 16x² - 1
The x-intercepts are the roots, i.e., the values of x for which f(x) = 0.
Use the Quadratic Formula to determine the roots.
x = [0±√0²-4·16(-1)]/[2·16] = ±√64/32 = ±8/32 = ±¼
f(x) = 16(x-¼)(x+¼) = (4x-1)(4x+1)

Sandy would probably take just as long as her mother because it says their mother takes 5 hours if decorating the house alone so if sandy is doing it alone it would also probably take her 5 hours as well. If this is wrong I’m sorry.
