Answer:
The two numbers can be -12 and 11, or 11 and -12.
Step-by-step explanation:
xy=-132
x+y=-1
-------------
x=-1-y
(-1-y)y=-132
-y-y^2=-132
-y^2-y-(-132)=0
-y^2-y+132=0
y^2+y-132=0
factor out the trinomial,
(y-11)(y+12)=0
zero property,
y-11=0, y+12=0,
y=0+11=11,
y=0-12=-12
x+11=-1 & x+(-12)=-1
x=-1-11=-12
x=-1-(-12)=-1+12=11

Answer: 1,296,000 inches
Step-by-step explanation:
Step 1: 100 yards to feet, is 300 feet, considering that 1 yard = 3 feet.
Step 2: 300 feet to inches is 3600, because one foot = 12 inches.
Step 3: 30 feet to inches is 360, because 30 x 12 = 360.
Step 4: 3600 x 360 = 1,296,000 inches.
