The perimeter = 20 and AC = 8
Now as it is not mentioned which sides are equal of the isosceles triangle ABC,
We have two possible situations.
1)
If AC is the base
In that case AB = BC
Now AC = 8, AB = x , BC = x
So x + x + 8 = 20
2x + 8 = 20
2x = 12
x = 6
AB = BC = 6
2)
IF AC is not the base,
Then
AC = BC or AC = AB
So BC = 8 or AB = 8
If AB = AC = 8
Then
BC + 8 + 8 = 20
BC = 4
So there are two possible lengths of BC
Either it is BC = 8 or BC = 6 or BC = 4

Answer:
1. -3/6 is negative, because it descends by 3 and goes over by 6.
2. My first answer literally gives the keyword negative, therefore it's a negative line because it has a <em>negative slope</em>.
1. -8/0 is undefined, because there is a rise but there is no run, which also means that it's a:
2. vertical line
1. -5/-10 simplifies to 5/10 or 1/2, which is positive because it rises by 5(or 1) and runs over by 10(or 2).
2. Thus, this means that it's a positive line since it has a <em>positive slope</em>.
1. 0/-2 is zero, because when you actually solve the equation it'll equal 0.
2. This means that it'll have a horizontal line since there is no rise but there is a run only.
Ethans is the correct one
Answer:
-2 ≤ x ≤ 6
Step-by-step explanation:
The first is ...
6 ≥ x
and it can also be written as ...
x ≤ 6
The second is
-2 ≤ x
The two inequalities can be combined into one compound inequality:
-2 ≤ x ≤ 6

<em>Comment on this answer</em>
I prefer the answer in this form because it puts the parts of the expression in the same order that they appear on a number line. It can also be written as ...
6 ≥ x ≥ -2
