Answer:
The value of c is 12.25
Step-by-step explanation:
we know that
A perfect square trinomial is of the form

In this problem we have

so
equate the equations

we have
the following equations
-----> equation A
and
-----> equation B
<u>Solve the equation A</u>



<u>Solve the equation B</u>


therefore

The value of c is 12.25
Answer:
27
Step-by-step explanation:
if 5n is equal to 135 the divide both sides with 5 and you will see 1n is equal to 27
Answer:
This is a geometric sequence with a common ratio of -4
Step-by-step explanation:
Take the second term and divide by the first term
-4/1 = -4
Take the third term and divide by the second term
16/-4 = -4
Take the fourth term and divide by the third
-64/16 = -4
This is a geometric sequence with a common ratio of -4
If you are asking which ratio is equivalent to 8 then it is neither. They are both simplified to 3:1. 54/18= 3, 18/6= 3. If you were asking if they were equivalent to each other the answer is yes.
