Answer:

  A.  2-x

Step-by-step explanation:

There are a number of ways you can look at this. You can look at the sign of 2, or you can look at the sign of x, or you can rewrite all of the expressions in standard form (decreasing powers of x). In standard form, we have ...

  A: -x +2

  B: x -2

  C: x -2

  D: x -2

Clearly, the different expression is choice A.

Simplify the radical expressions pleaseeeeee help I haven’t done algebra in 2 years
sweet [91]
For the first one, simplify the radicals. The 3 root 8 can be rewritten as 3 root 4 root 2, which turns into 6 root 2. The 4 root 3 can’t be simplified, so just multiply. 6*4=24 and the root 2*root 3 turns into root 6. So your answer for the first one is 24 root 6.

For the next one you can’t have a radical in the denominator so just multiply by root 3/ root 3, which gives you 6 root 3/3 which simplifies into 2 root 3.

OleMash [197]
Given that a<span> passenger elevator in the sears tower in Chicago can lift people 960 feet in 1 minute and 30 seconds (1.5 minutes). This means that the lift is travelling with a speed of:

</span>speed= \frac{distance}{time} = \frac{960}{1.5} =640ft/min
<span>
If the elevator lifts cargo through the same height in 2 minutes and 30 seconds (2.5 minutes), then the speed is given by:

</span>speed= \frac{960}{2.5} =384ft/min<span>
