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:
15
Step-by-step explanation:
hope this helps!
<u>⇒If the unknown x;</u>
48 + x = -18
⇒<span><u>Known unknowns to one side into the other side .</u>

x = -18-48
x=-66

Answer:
this is an iscoceles triangle.
I know this because 2 of the sides are equal in length
Therefore,
AB=AC
3x-5=-2x+15
x-5=15
x=20
if x=20 then BC=2(20)
BC=40
Step-by-step explanation:
13 packs a year. 6.50 (.50 comes from 1/2) since the question states that she uses 6_1/2 packs of pencils in the first “1/2” of the year we need to multiply the 6_1/2 by 2 and we get our answer.
