The answer is going to be 2/15
Answer:

Step-by-step explanation:
A perfect square trinomial is defined as an expression that is obtained from squaring a binomial equation. The perfect square trinomial is in the form of
.
The given expression is :

The co-efficient of the x-term in
is '16'.
So half of the term 16 ,

and 
Now add 64 to the expression:

Therefore, the perfect square trinomial is

Esa expresión es una simple suma, un número negativo más uno positivo ejemplo: le debes 3 dólares a tu hermano lo cual es negativo, pero tu padre te regala 4 dólares lo cual es una valor positivo porque lo tienes en tus manos, pagas los 3 que debes y te sobra un dólar de los 4 que tenias, ahora ya no debes nada y aún te sobra un dólar.
To find miles per hour:
3 3/5 miles divided by 4/5 hour
3 3/5 = 5*3 + 3 = 18/5
18/5 divided by 4/5 equals
18/5 times 5/4
The fives cancel out, and we have 18/4 which reduces to 9/2 or 4 1/2 miles per hour :)
The answer to a division problem is the quotient
