Answer:
(x+4)^2 Choice A
Step-by-step explanation:
x^2 + 8x + 16
what 2 numbers multiply together to give you 16 and add together to give you 8
1*16 = 16 1+16 = 17 no
2*8 = 16 2+8 = 10 no
4*4 = 16 4+4 = 8 yes
(x+4) (x+4)
(x+4)^2
Answer:
The first thing you do is make the denominators equal on both sides.
Step-by-step explanation:
As a example if you have the equation:
+
=
you would multiply the denominator by the smallest multiple. I would do 2 * 5= 10
this would make the equation

next you have to do the same with the numerator.
so sence you multiplied the
by five you will get 
same with the other fraction except you multiplied it by two.
x 2 = 
next you add and simplify if needed
