Question

Help with #4!!! I’ve tried to figure it out but I can’t.

Answer 1

a

Explanation:

all you do is divied the top then you take from

Answer 2

(x^3 + 6x^2) / (80x + 64)

Last option

Explanation:

Top:

1/8 + (x+4)/(16)

= 2/16 + (x+4)/(16)

=(2+x+4)/16

=(x + 6)/16

Bottom:

(x+4)/x^2 + 4/x

= (x+4)/x^2 + 4x/x^2

=(x + 4 + 4x)/x^2

= (5x+4) / x^2

So now you have:

(x + 6)/16 / (5x+4) / x^2

= (x + 6)/16 * x^2 / (5x+4)

= (x^3 + 6x^2) / (80x + 64)

Answer is the last one
