Answer:
Step-by-step explanation:
Let's examine the following general product of two binomials with variables x and y in different terms:
so we want the following to happen:
Notice as well that 
means that those two products must differ in just one unit so, one of them has to be negative, or three of them negative. Given that the product 
, then we can consider the case in which one of this (b or d) is the negative factor. So let's then assume that 
are positive.
We can then try combinations for such as:
Just by selecting the first one 
we get that 
and since
This quadratic equation give as one of its solutions the integer: d = -2, and consequently,
Now we have a good combination of parameters to render the factoring form of the original trinomial:
which makes our factorization:
2 trips. The volume of the truck bed is 3.75 cubic meters, and they need 7 cubic meters. 3.75 times 2 is 7.5 cubic meters. It cannot have less than a full trip, and it cannot transport the whole load in one trip, so in order for the whole load to be delivered, it is necessary for the truck to make 2 trips.
Um....Where is the question.....or is that it
Divide 7 by 19.
The answer is 0.368421053
