The triangle has two equal sides and two equal angles :)
Because both angles are the same, and are in the same spot in the congruent triangles, we can set these angles up to equal each other:

Add x to both sides:

Subtract 4 from both sides:

Divide both sides by 4 to get x by itself:

The value of x is
17.
The statement is false, because -2 is larger than -3.
<h3>Is the statement true?</h3>
We know that -3 is a lower bound for the real zeros of f(x).
So, if we define k as the smallest real zero of f(x), we have:
-3 < k.
Then we can take, for example, k = -2.5
That is an allowed value for the real zero.
In that case, -2 is not a lower bound, because is false that:
-2 < k = -2.5
Then if -3 is a lower bound for the real zeros of f(x), we can't assume that -2 is also a lower bound (because -2 is larger than -3).

18 is not a function because a function is when exactly ONE x value is paired with ONE y value.
19 is not a function because of the same logic for number 18
The numerator for the fractions 1/6 and 1/8 is equivalent.
