The model represents a polynomial and its factors.
.
which equation is represented by the model?

a.) x^2 – 2x – 3 = (x – 3)(x + 1)
b.) x^2 – 4x + 3 = (x – 3)(x – 1)
c.) x^2 + 2x + 3 = (x + 3)(x – 1)
d.) x^2 + 4x – 3 = (x + 3)(x + 1)

Use the distributive law to multiply. 3(4x + 5y + 6)

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
