The hard drive of Jeremy’s computer had an initial storage capacity of 80 gigabytes. He then upgraded the hard drive capacity of his computer by 3.1 times the initial capacity. He also bought an external drive with a storage capacity of 60.5 gigabytes.

A) Calculate the new capacity, in bytes, of the hard drive of Jeremy’s upgraded computer. Write your answer in scientific notation.

B) Find the total storage capacity, in bytes, of Jeremy’s upgraded computer and find the external drive. Write your answer in scientific notation.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

hope i could ! : )

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
