Factor the polynomial.
Degger [83]
It is answer choice A because you have to take the the GCF of each number which is 2x. Then if you were to divide the numbers by 2x you would put those numbers in the brackets. 
2x( x^{2} +2x+4) because 2x^3/2 x =  x^{2} and 4 x^{2} /2x = 2x and 8x/2x = 4

How would you estimate whether 27/50 is closer to 1/2 or 1 without using a number line? Explain.
Ivahew [28]

Answer

Find\ out\ the\ how\ would\ you\ estimate\ whether\ \frac{27}{50}\ is\ closer\ \frac{1}{2}  to\ or 1\ without\ using\ a\ number\ line .

To prove

As\ the\ value\ of\ \frac{27}{50}\ in\ decimal\ form.

= \frac{27}{50}

= 0.54

As\ the\ value\ of\ \frac{1}{2}\ in\ decimal\ form.

= \frac{1}{2}

= 0.5

As\ the\ value\ of\ 1 \ in\ decimal\ form.

= 1.00

Now we find out the mid point of the 0.5 and 1.00 .

Mid\ point = \frac{1.00+0.5}{2}

(Mid point is the point lies middle of a line segment .)

Mid point = 0.75

Thus

0.54< 0.75

This shows o.54 lies between 0.5 and 1.00

This means 0.54 lies right to 0.5 and left from 1.00 .

Therefore

\frac{27}{50}\ lies\ right\ to\ \frac{1}{2} and\ left\ from\ 1.
