If u subtract 6-9 u would get a -3 because the 9 is bigger than the 6 so thats how you get a -3.
Answer:
The explicit form is 
Step-by-step explanation:
The explicit form of a geometric sequence is given by:
where an is the nth term, a is the first term of the sequence and r is the common ratio.
In this case:
a=162
The value of the common ratio is obtained by dividing one term by the previous term.
For the first and second terms:
108/162=2/3
For the second and third terms (In order to prove that 2/3 is the common ratio)
72/108=2/3
Therefore:
r=2/3
Replacing a and r in the formula:
The formula for b from the given area is equal to (2A / h).
As given in the question,
Formula to find area of a triangle is equal to A = (1/2) b h
b represents the base of the triangle
h represents the height of the triangle
A = (1/2) b h
Multiply both the side by 2 in area formula
2A = b h
Divide both the side by h
b = (2A) / h
Therefore, the formula for b from the given area is equal to (2A / h).
The complete question is:
The formula A = (1/2)b h represents the area of a triangle where A represents the area, b is the base of the triangle and h is the height of the triangle. 1. Solve this formula for b.

Answer:
x = 4.2
Step-by-step explanation:
14.1² + x² = 14.7²
198.81 + x² = 216.09
216.09 - 198.81 = 17.28
√17.28 = 4.15
x = 4.15
Round to nearest tenth
x = 4.2
