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:

$A=lw$

l - length

w - width

We have

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

Substitute:

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

Use FOIL (a + b)(c + d) = ac + ad + bc + bd

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

combine like terms

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

What is the range of y = log Subscript 8 Baseline x? all real numbers less than 0 all real numbers greater than 0 all real numbe

Doss [256]

Answer:

All real numbers

Step-by-step explanation:

To find the range of the function $y=\log_8x,$ draw the graph of ths function (see attached diagram for details).

Since the base of the logarithm is $8>1,$ the graph is increasing and passes through the point (1,0).

The domain of this function is

$x>0.$

The range of this function is

$y\in (-\infty, \infty)$

or all real numbers.
