Hence, the value of x is 1.
<h2>What is length?</h2>
Length is defined as the measurement or extent of something from end to end. In other words, it is the larger of the two or the highest of three dimensions of geometrical shapes or objects.
<h3>How to solve?</h3>
It can be observed that the given 2 triangles are congruent.
we know, for congruent triangles, the length of corresponding sides is equal.
Hence,
AB = DE
4x - 1 = x + 2
3x = 3
x=1
Therefore, the value of x is 1.

Answer:
We are given
Scientist begins with 150 milligrams of a radioactive substance
so,
we can use formula
we can plug Po=150
After 29 hours, 75 mg of the substance remains
so, at t=29 , P=75
we can plug it
now, we can solve for k
now, we can take ln on both sides
now, we can plug it back
and we get
we can plug t=33
we get
