Answer:
How to Find Area and Perimeter: 11 Steps (with Pictures ... To find the perimeter of a shape, measure each of the sides and add them all together. To find the area of a square, rectangle, or other parallelograms, multiply the length by the width. If you need to find the area of a different shape, you will need to know the formula for that shape.
 
        
                    
             
        
        
        
Answer:
 
 

You gave the explicit form.
Step-by-step explanation:
You gave the explicit form.
The recursive form is giving you a term in terms of previous terms of the sequence.
So the recursive form of a geometric sequence is  and they also give a term of the sequence; like first term is such and such number. All this says is to get a term in the sequence you just multiply previous term by the common ratio.
 and they also give a term of the sequence; like first term is such and such number. All this says is to get a term in the sequence you just multiply previous term by the common ratio.
r is the common ratio and can found by choosing a term and dividing by the term that is right before it. 
So here r=-3 since all of these say that it does:
-54/18
18/-6
-6/2
If these quotients didn't match, then it wouldn't be geometric.
Anyways the recursive form for this geometric sequence is
 
 

 
        
             
        
        
        
Answer:
a.) b⁷÷b⁴
 = <u>b⁷</u>
 b⁴
 = b^7-4
 = b³
b.) <u>x </u><u> </u><u>×</u><u> </u><u> </u><u>x⁵</u>
 x² × x 
 = <u>x</u><u>^</u><u>1+</u><u>5</u>
 x^2+1
= <u>x⁶</u>
 x³
= x^6-3
= x³
