Answer:x-5

Step-by-step explanation:

-6(2x+1)=54

Brut [27]

The entire interval over which the function, f(x), is positive is (-∞,1).

<h3>What is a function?</h3>

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Each element of X receives exactly one element of Y when a function from one set to the other is used. The set X is referred to as the function's domain, while the set Y is referred to as the function's codomain.

According to the question,

The function has positive values corresponding to the interval from negative infinity to one.

The length of a rectangle is 3 inches more than its width.
BlackZzzverrR [31]

Answer:

X=15

Step-by-step explanation:

Ignore the increase for equasion. This is factored in but irellevent. Orignal x value is 13, but increases to 15, and orignal x value is not needed for this equasion. (its there to confuse you)

L+L+W+W=66.

(w+3) +(w+3) +w +w = 66

(4xw) + 3 +3= 66

4 x w = 66 -3 -3

4 x w =60

60/4= 15.

L= 15+ 3 =18

W = 15.

W + W + L + L

15 + 15 + 18 +18 =66
