Answer:
43
Step-by-step explanation:
43 is the answer. here you go
0= -3x+9
-9=-3x
3=x
Final answer: x=3
There is only one zero because it is linear, and can therefore only cross the x axis once.
Answer:
width=x
perimeter=80
or 2(x+l)=80
so l=length=40-x
so the area=x(40-x)
the area can never be 0
x(40-x)>0
this gives the domain as 0
Step-by-step explanation:
Answer:
Two pairs of parallel sides
All sides congruent
Four right angles
