Mathematics: Books at a library sale are sold for $3.50 each. A function, y = 3.50x can be used to generate an input/output table for this scenario. Which statement is true about an accurate graph of this data? The data is continuous, so it does not matter whether or not the points are in a line. The data is discrete, so the graph is a series of unconnected points. The data is continuous, so the graph is a series of unconnected points. The data is discrete, so the points are connected with a line. I will give

if you mean (a+b)^2 then the rule is..

(a+b)^2=

a^2+2ab+b^2

Step-by-step explanation:

its simply a property of math or a formula and if u want proof this works try it with any two terms like this for example:

(a+b)^2=

(2+7x)^2=

Subsitute.

a^2+2ab+b^2

2^2+2*2*7x+2x^2

so.. 4+28x+4x^2

or 2x^2+28x+4 is your answer :)

and if you solve this using the

(2+7x)(2+7x) looping method thingy

then you will see that you get the same answer of

2x^2+28x+4.

this proves that the formula works.
