I don't either....I'm just taking a guess....LOL!!!!

Anyway.....they have two choices......!!!!

I'm not sure h7, but I think the questioner wants to know the factor tree of 454....so we have

454 =

227 X 2

Both of these are prime.....so.....that's it !!!

Let's look at h7's answer

Note that 40 can be factored as 2³ x 5

And 50 can be factored as 5² x 2

Now we can find the LCM by taking each different factor along with the highest factor on that power.

2³ x 5² = 

8 X 25 =

200  ........just as h7 found

Very nice, h7......

I don't see any choices, but the answer is that all real numbers greater than 16 and less than 25 would have square roots between 4 and 5.

We have to know how many miles per gallon the car gets before we can answer this....

(2/3) + (1/11)    the common denominator is 33

So 2/3  = 22/33    and 1/11 = 3/33

Can you take it from there???

These two graphs have exactly the same shape....the graph of y = (x +3)^3 is just the graph of y = x^3 shifted 3 units to the left.....

A = 2500(1 + .08/4)^15*4 = 2500(1 + .02)⁶⁰
