Answer:

I don't know if this is correct but wouldn't it be 560?

Step-by-step explanation:

If you have 10 on one side, you divide 10 by 1/4 to get 40. So you need 40 blocks to fill one side, and 3 1/2 on the other only needs 14. 14*40=560.

So, Option B is correct.

Step-by-step explanation:

We need to solve the inequality: $|x-4|< 3$

Solving:

$|x-4|< 3$

The absolute rule says that if |u|<a and a>0, then -a<u<a

So, applying absolute rule:

$|x-4|< 3\\-3$

We can write it as:

$x-4>-3\,\,and\,\,x-4-3+4\,\,and\,\,x1\,\,and\,\,x$

Combining the intervals:

$1$

So, Option B is correct.
