Answer:
The answer to this question can be defined as follows:
In option 1, She buys 4 memory cards.
In option 2, The cost of memory is $40
Step-by-step explanation:
Given:
Available space is = 105 GB
required space = 1000 GB
256 GB memory cost $10.
Find needed memory:
= 1000 GB - 105 GB
= 895 GB
∴ the available memory is 256 GB.
∵ 256 × 4 = 1024 GB
The total memory she have = 1024 + 105 = 1129 GB
And she needs to buy 4 memory cards.
The cost of the four memory cards is= 4 ×10 = $40.
It is the answer number 2

Answer:
16x^2 -48xy^3 +36y^6
Step-by-step explanation:
(4x-6y^(3))^(2)
FOIL
(4x-6y^3) (4x - 6y^3)
first: 4x*4x = 16x^2
outer : 4x (-6y^3) =-24xy^3
inner : 4x (-6y^3) =-24xy^3
last: -6y^3 * - 6y^3 = 36y^6
Add them together
16x^2 -24xy^3-24xy^3+36y^6
Combine like terms
16x^2 -48xy^3 +36y^6
Answer:
The strategies (2), (3) and (5) can be applied.
Step-by-step explanation:
In this case we need to compute the product of 629 × 100.
The product can be found in the following ways:
- multiplying (600 + 20 + 9) x 100

- putting 2 zeros on the end of 629

- multiplying (6,000 + 200 +90) x 10

Thus, the strategies (2), (3) and (5) can be applied.
