An identity, in mathematics, is a relation between A and B that would result to an equality of the two. It should be expressed as A = B wherein both values has some variables that would produce the same value no matter what will be the values used for the two functions. We are given the equation as follows:
a(2x+3)=9x+15+x
To determine the value of a that would make this equation an identity, we assume a value for x. We can assume a value of 1. We do as follows:
a(2 + 3) = 9 + 15 +1
5a = 25
a = 5
Therefore, the value of a would be 5.
three hundred fourteen thousand and two hundred seven.
AB=7.6 IS THE ANSWER OF THIS QUESTION
9.1 is less than half of 3576, so it's going to round down to
0. (mental math)
<em>I'm not sure if you were also asking for the actual value because of the wording, so here it is if you need it</em>.
As a fraction,

.
(multiply both the top and the bottom by 10)
As for the actual decimal value, it's something like 0.0025447....You can find this out using long division (you're going to have to know the multiples up to 10 of 3576, so list those off to the side) or simply a calculator. As for handling the decimal, just divide into the 9.1 like a normal number (only the digits are important when you're doing the long division) and bring up the decimal point when you're done. You might also need to use zeroes as placeholders. (9.1 = 9.10000...)
