Express the area of the entire rectangle.
Cloud [144]

Answer:

\huge\boxed{A=x^2+12x+35}

Step-by-step explanation:

The formula of an area of a rectangle:

A=lw

<em>l</em><em> - length</em>

<em>w</em><em> - width</em>

We have

l=x+7\\\\w=x+5

Substitute:

A=(x+7)(x+5)

Use FOIL <em>(a + b)(c + d) = ac + ad + bc + bd</em>

<em></em>A=(x)(x)+(x)(5)+(7)(x)+(7)(5)\\\\A=x^2+5x+7x+35<em></em>

combine like terms

A=x^2+(5x+7x)+35\\\\A=x^2+12x+35

saul85 [17]

Answer:6.1

Step-by-step explanation: the equation is 6n=30.5+n. the first thing you you do is subtract n on both sides which would be 6n-n which gives you 5. the equation now is 5n=30.5. now what you do is divide 5 on both sides so it would be 30.5/5 and that gives you 6.1
