Answer:
5(6)81 because the are
Step-by-step explanation:
6•82
The height of the model in inches would be 6. if you multiply 30 until it reaches 180 you will have 6.
General term of a geometric sequence is
a(n)=a(1)×r^(n-1)
a1=5
a2=5×6=30
a3=5×6²=180
a4=5×6³=1080
Using the quadratic equation we get:

Factoring out 2 we get

Factoring out the imaginary number:

So b.
Rahul use addition property of equality in step 2.
Solution:
The image of the question is attached below.
Step 1:

combine like terms together.

To make the denominator same multiply and divide 2x by 5.
Step 2:

By addition property of equality, add
on both side of the equation.

Step 3:

Step 4:
Multiply by
on both side of the equation.

Hence Rahul use addition property of equality in step 2.
