Answer:

b. $(x - 2) ^{2} - 36$

d. $(x - 2) ^{2} - 36$

Step-by-step explanation:

$(x + 4)(x - 8) \\ \\ = {x}^{2} - 8x + 4x + 4( - 8) \\ \\ = {x}^{2} - 4x - 32 \\ \\ = {x}^{2} - 4x + 4 - 4 - 32 \\ \\ = {x}^{2} - 4x + {2}^{2} - 36 \\ \\ = (x - 2) ^{2} - 36$

What is the relationship between the 6s in the number 660,472

scoundrel [369]

Answer:
The first 6 is 10 times greater than the second one

Explanation:
The given number is 660,472
This number can be rewritten as:
660,472 = 600,000 + 60,000 + 400 + 70 + 2

Now, comparing this to the place-value chart shown in the attached image, we would find that:
The first 6 represents the hundred thousands of the number
The second 6 represents the ten thousands of the number
The 0 represents the thousands of the number
The 4 represents the hundreds of the number
The 7 represents the tens of the number
The 2 represents the ones of the number

Now, we are comparing the values of the 6s:
The first 6 represents the hundred thousands of the number
The second 6 represents the ten thousands of the number
This means that:
The first 6 is 10 times greater than the second one

Hope this helps :)
