Answer:

$x^2+8x+12$

Step-by-step explanation:

The area of a rectangle formula is length times width.

The length of this rectangle is $(x+2)$ , and the width of this rectangle is $(x+6)$

Thus, the area of the rectangle is $(x+6)(x+2)$ . This can be expanded using FOIL.

First $x(x)=x^2$

Outer $x(2)=2x$

Inner $6(x)=6x$

Last $6(2)=12$

The two x terms combine, making 8x, and the answer is $x^2+8x+12$

John read the first 1 1 4 114114 pages of a novel, which was 3 33 pages less than 1 3 3 1 ? start fraction, 1, divided by, 3, en

damaskus [11]

We are given statement " John read the first 114 pages of a novel, which was 3 pages less than 1/3 of the novel".

Let us assume total number of pages of a novel = p pages.

3 less than 1/3 of total pages = 114.

3 less then 1/3 of P is = 114.

$\frac{1}{3}P- 3 = 114$

<h3>Therefore, required equation for number of pages of a novel is </h3><h3> $\frac{1}{3}P- 3 = 114$ .</h3>

Answer:

y = 75

z = 43.3

Step-by-step explanation:

To find the value of y we use the trigonometric identity Sine.

$sin\ 30 = \frac{y}{150}\\\\y=150*sin30\\y= 75\\$

Now to find the value of z we can use the trigonometric identity Tangent.

$tan\ 60=\frac{y}{z}\\\\z=\frac{y}{tan\ 60}$

We know the value of y is 75 so it becomes,

$z=\frac{75}{1.732} \\\\z=43.3$

I was reading the comments from the other person who answered and I'm guessing both of you don't know what Mean Absolute Deviation (MAD) means.... I'm going to show you an example.......

For example:

2, 2, 4, 4

2 + 2 + 4 + 4 = 12 ÷ 4 = 3

12 ÷ 4 (because there are exactly 4 numbers)

Mean: 3

Mean Definition: The mean is the average of the numbers. To calculate it: add up all the numbers, then divide by how many numbers there are.

Mean Absolute Deviation (MAD):

2, 2, 4, 4 Mean: 3

(2 - 3) + (2 - 3) + (4 - 3) + (4 - 3) = 4 ÷ 4 = 1

Mean Absolute Deviation: 1

4 ( because I subtracted all the numbers and then added it all together) ÷ 4 (because there are exactly 4 number)

I hope your getting it because if you do it on paper it's easier.

Hope these helps!!!! Happy Holidays!!!! (:
