D. x(x+5)^2

Step-by-step explanation:

Factor out an x first and then factor the rest like you normally would

x(x^2+10x+25)

Only factor the inside now. You need two numbers that multiply together to give you 25 and add to get you 10, which is 5.

When factored, it becomes:

x(x+5)(x+5)

(x+5)(x+5) is the same as (x+5)^2

Multiply 3/5 * 12= 3*12/5*1 = 36/5 
Then multiply both numerators and denominators. Result fraction keep to lowest denominator. So 36/5= 7 1/5 which equals 7.2

Multiply 1/4 * 14 = 1*14/4*1 -14/4 =7/2
Then multiply both numerators and denominators. Result fraction keep to lowest denominator. So 7/2 = 3 1/2 which equals 3.5

First you need to convert 2 3/20 = 2*10+3/10 =23/10
Then multiply 23/10 * 10 = 23*10/10*1
Then multiply both numerators and denominators. Result fraction keep to lowest denominator. So 23*10/10*1 = 230/10 which equals 23. 

I hope that this helps! :)
