Answer: 15
Step-by-step explanation:
x:9 = 25:15
x = 25:15*9 = 15
10/1 = 43.5/x
cross multiply
10x=43.5
divide by 10 on each side
x = 4.35
it will take 4.35 minutes
In this case we have the following trinomial:
By definition, the factorization is a technique that consists in the mathematical decomposition of an expression, in the form of a product. Having said that, we can factor the given trinomial in the following way:
We look for two numbers that when multiplied give as result 42, and when summed give as result -13.
The numbers that meet these two conditions are -6 and -7 by:
So, we have:
Answer:
The binomials associated with the given trinomial are
and 
.
