3 0

x = - 2 and x = 3

to find the zeros set f(x) = 0

3x² - 3x - 18 = 0

divide through by 3

x² -x - 6 = 0

(x - 3)(x + 2) = 0 ⇒ x = - 2 and x = 3 are the zeros

A room is 20 feet long, 12 feet wide, and 10 feet high. What is the maximum distance from one corner to another
exis [7]

Answer:

25.38

Step-by-step explanation:

Its a 3-D block, so you have to find the distance from on corner to the opposite corner of the roof, but first find the distance from corner to corner on the floor.

20^2+12^2=c^2

400+144=544=c^2

c=\sqrt{544}

then find corner of floor to opposite roof corner.

100+544=644=c^2

c=\sqrt{644}

so its about 25.38 feet
