The simplified expression is (4x+7)^2=16x^2+56x+49

Explanation:

The expression that we have in this problem is

(4x+7)^2

We want to simplify this expression: in order to do so, we apply the rule to solve the square of a binomial:

(a+b)^2=a^2+2ab+b^2

Where in our expression, we have:

a=4x\\b=7

So, the various terms are:

a^2=(4x)^2=16x^2\\2ab=2(4x)(7)=56x\\b^2=7^2=49

Therefore, the final expression becomes

(4x+7)^2=16x^2+56x+49

Montano1993 [528]

The correct answer to this open question is the following.

Unfortunately, you forgot to attach the text. Without the text, we do not know what is its content and can not support the answer with that evidence.

However, trying to help you, we can comment on the following.

The role of a forensic artist is to sketch the faces of suspects. These forensic artists talk to victims of a crime in order to interpret the description of suspects and draw the most precise face so police can investigate the case. They only base their sketches on the description of the witnesses or the victims. That is why their work is of the utmost importance for police investigations.
