The length of a picture is 15.75 inches shorter than twice the width. If the perimeter of the picture is 106.5 inches, find its

Vladimir79 [104]

Answer:

Length = 45.37 in

Width = 30.56 in

Step-by-step explanation:

Let the width of the picture be 'w' inches.

Given:

Perimeter of the picture is, $P=106.5\ in$

Length is 15.75 inches shorter than twice the width. So, length is:

$l=2w-15.75$

Now, we know that the perimeter of a rectangular shape is given as the sum of all of its side. So, the picture is also of rectangular shape and hence the perimeter is given as:

$P=2l+2w$

Plug in the values of 'l' and 'P' and solve for 'w'. This gives,

$106.5=2w-15.75+2w\\106.5=4w-15.75\\106.5+15.75=4w\\4w=122.25\\w=\frac{122.25}{4}=30.56\ in$

Therefore, the width of the rectangular picture is 30.56 inches.

Length of the picture is, $l=2(30.56)-15.75=61.12-15.75=45.37\ in$

So, length of the picture is 45.37 inches and width is 30.56 inches.

11. What is the remainder if x2- 7x - 4 is divided by x<br> - 2? a. 4 b. -14 c. 2 d. -2

Likurg_2 [28]

<h2>Solving for the Remainder with the Remainder Theorem</h2><h3>Answer:</h3>

$-14$

<h3>Step-by-step explanation:</h3>

Given:

$x^2 -7x -4$ divided by $x -2$ .

<em>Please refer to my Answer from this Questions to know more about the Remainder Theorem:</em>

<em><u>brainly.com/question/24591570</u></em>
<em><u>brainly.com/question/24591554</u></em>
<em><u>brainly.com/question/24655500</u></em>

Let $P(x) = x^2 -7x -4$ so that when we divide $P(x)$ by $x -\blue 2$ the remainder will be $P(\blue 2)$ according to the Remainder Theorem.

Solving for $P(2)$ :

$P(\blue 2) = (\blue 2)^2 -7(\blue 2) -4 \\ P(\blue 2) = 4 -7(\blue 2) -4 \\ P(\blue 2) = 4 -14 -4 \\ P(\blue 2) = -14$

The remainder is $-14$ .
