The possible values for the missing number that make the given expression the square of a binomial is; 81
<h3>Binomial Expression</h3>
We are given the expression;
x² + 18x
- Now, if we consider the binomial; x ± b
Squaring that gives us;
x² ± 2ax + b²
Comparing this expression to the one we are given we can say that;
±2ax = 18x
±a = 18/2
a = ±9
Thus,we will have;
(x + 9)² as our expression which is;
x² + 18x + 81
Therefore, the missing number is 81.

Prior to servicing the IDG, you must make sure that it's properly covered to avoid dangerous oil spray.
<h3>What is an
IDG?</h3>
An IDG is acronym for integrated drive generator and it can be defined as an electrical power (electricity) for an aircraft or airplane.
As a safety precaution, you must make sure that it's properly covered to avoid dangerous oil spray prior to servicing the integrated drive generator (IDG).

The explicit rule for this geometric sequence 29,23,2,6, is n = 29 × (29/23)^(n - 1)
<h3>How to write explicit rule</h3>
Second term, a×r = 23
23 = 29 × r
23 = 29r
r = 29/23
The explicit formula is given by
nth term = ar^(n - 1)
n = 29 × (29/23)^(n - 1)
Where,
nth term = number of terms
