The length is 18 and it's width is 10 because 10+8=18 and 18•10=180

<h2>Answer with Step-by-step explanation:</h2>

The area of a rectangular wall of a barn is 180 square feet.

Its length is 8 feet longer than the width.

Let  w be the width of wall of barn

then, Length of wall of barn=w+8

we know that area of rectangle=Length×width

so, (w+8)w=180

w²+8w=180

w²+8w-180=0

w²+18w-10w-180=0

w(w+18)-10(w+18)=0

(w-10)(w+18)=0

either w-10=0  or w+18=0

w=10 or w= -18

w= -18 not possible

so, w=10

w+8=18

So, Length of wall of barn= 18 feet

and Width of wall of barn= 10 feet

If | 8x -2 | &lt; 4, Which of the following is true of x? Explain as well.
wariber [46]

The true expression of the variable x in the inequality expression given as |8x - 2| < 4 is -0.25 < x < 0.75

<h3>What are inequality expressions?</h3>

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

<h3>How to determine the true expression of the variable x?</h3>

The inequality expression is given as

|8x - 2| < 4

Divide through the above equations by 2

So, we have the following inequality expression

|4x - 1| < 2

Remove the absolute value sign from the inequality expression

So, we have

-2 < 4x - 1 < 2

Add 1 to all sides of the above inequality expression

So, we have

-1 < 4x < 3

Divide through the above inequality expression by 4

So, we have

-0.25 < x < 0.75

Hence, the true expression of the variable x in the inequality expression given as |8x - 2| < 4 is -0.25 < x < 0.75

What is the inverse of the function f(x) = 2x – 10?
Lana71 [14]

Answer:

h(x)=\dfrac{x}{2}+5

Step-by-step explanation:

You are given the function f(x)=2x-10. To find the inverse function f^{-1}(x) do such steps:

1. Rewrite the function f(x) as

y=2x-10

2. Express x in terms of y:

y+10=2x\\ \\x=\dfrac{y}{2}+5

3. Change x into y and y into x:

y=\dfrac{x}{2}+5

Now, the inverse function is

f^{-1}(x)=\dfrac{x}{2}+5

If b = 3, then 3x + y = 1 and bx - y = 3 are parallel.<br> True or <br> False ...?
Ulleksa [173]
I am absolutely sure that the task <span> b = 3, then 3x + y = 1 and bx - y = 3 is NOT parallel, which means that the statement represented above is FALSE.
To make sure you can check it using : </span>y=-3x+1&#10;&#10;y=3x-3 Hope now it's obvious. Regards!
