To perform this check, you must use the following theorem: 
is a lower bound for the zeroes of 
if, when divide by 
, the quotient and the remainter alternate signs.
Since the long division yields the result
You can see that the signs don't alternate (the last two terms are positive). So, -1 is not a lower bound.
In fact, the actual roots of the polynomial are -3, -2, 1, 3, so as you can see there are roots smaller than -1.
Volume=length times width times height
this should be easy
a.
the volume of a box is 2.5 times 1 times 1 or 2.5 cubic meters
b.
number of boxes times volume per box=volume of container
number of boxes=volumecontainer/volumebox
find volumecontianer
volumecontainer=5 times 2 times 3=30 cubic meters
number of boxes=30/2.5
number of boxes=12
12 boxes needed to fill container
c.
box
1m=100cm
1m by 1m by 2.5m convert so (times everybody by 100)
100cm by 100cm by 250cm
multiply
2,500,000 cubic centimeters
Answer:
y-int is -4 or (0,-4)
Step-by-step explanation:
That is the point where the line crosses the y-axis
Answer:
EH= 14
DF= 28
Step-by-step explanation:
Answer:
11h - 11
Step-by-step explanation:
13h - 7 - 2h - 4
combine like terms: 13h + (-2h) = 11h
11h -7 -4
combine like terms again: -7 + (-4) = -11
11h - 11
