the length of the rectangle is twice its width. write and solve a system of linear equations to find the length L and width W of

xz_007 [3.2K]

Answer:

2 ( m + 2 m) = 36 is the required linear equation

Length of the rectangle is 12 ft and width = 6 ft

Step-by-step explanation:

Let the width of the rectangle = m ft.

So, the length of the rectangle = 2m ft.

Perimeter of rectangle = 36 ft

Now, PERIMETER OF THE RECTANGLE = 2(LENGTH + WIDTH)

⇒2 ( m + 2m) = 36

or, 2 x 3m = 36

⇒ 6m = 36 , or m = 36/6

⇒ m =6 ft

So, the Width of the rectangle; = m = 6 ft

and the Length of the rectangle = 2 m = 2 x 6 = 12 ft.

Find the mean of this data set: {– 78, -12, 3, – 44}

blagie [28]

Answer:

Answer: A. -32.75

$\dashrightarrow{ \tt{mean = \frac{ \sum f(n)}{n} }} \\$

• f(n) are the values of the set

• n is the number of items

$\dashrightarrow \: { \tt{mean = \frac{ - 78 + ( - 12) + 3 + ( - 44)}{4} }} \\ \\ \dashrightarrow \: { \tt{ \frac{ - 131}{4} }} \\ \\ \dashrightarrow \: { \boxed{ \tt{mean = - 32.75}}}$
