Option B) (x + 3)^2 − 5 is the correct answer
Step-by-step explanation:
Given expression is:
We will solve eah expression in the options to chek which is equivalent to given expression
So,
<u>A) (x + 3)^2 + 5</u>
NOT equivalent
<u>B) (x + 3)^2 − 5</u>
Equivalent
Hence,
Option B) (x + 3)^2 − 5 is the correct answer

Answer:
-1.6
Step-by-step explanation:
4x +8y=0
y=0.8 ⇒
- 4x+8*0.8=0
- 4x+6.4=0
- 4x=-6.4
- x= -6.4/4
- x= -1.6
Answer:

The equation for circumference is
Since you have the diameter you can either divide the diameter (d) by two to get the radius (r), or you can divide two from the equation to give you
So the circumference is 33*pi meters, approximately 103.62 meters
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.
