Answer:

Width of one side is 30 inches, Length of one side is 22 Inches and Areas is 660 Inches Squared

Step-by-step explanation:

W= 8 + L

P = ( W x 2 ) + ( L x 2 )

104 = 2( 8 + L ) + ( L x 2 )

104 = 16 + 2L + ( L x 2 )

104 = 16 + 2L + 2L

104 = 16 + 4L

-16 -16

88 = 4L

88 / 4 = 4L / 4

22 = L

W = 8 + 22

W = 30

Area = L x W

A = 22 * 30

A = 660

Answer:

The width of the rectangle is 56 and the length is 48

Step-by-step explanation:

divide the perimeter in half (52 + 52)

then subtract 4 from one of the 52's

you get the answer of 56 and 48

Your answer can be checked by conferming that 56 - 48 = 8 so the width of a rectangle is 8 inches longer than its length.

Answer:

See below

Step-by-step explanation:

x(x-2y)-(y-x)2

Final result :

-y2

Step by step solution :

Step 1 :

Equation at the end of step 1 :

x • (x - 2y) - (y - x)2

Step 2 :

2.1 Evaluate : (y-x)2 = y2-2xy+x2

Final result :

-y2

Check the picture below.

$\bf \cfrac{8}{12}=\cfrac{x+4}{2x+1}\implies 16x+8=12x+48\implies 4x=40
\\\\\\
x=\cfrac{40}{4}\implies x=10$

What equation in slope intercept form represents the line that passes through the points (4,6) and (8,0)

madam [21]

Answer:

The slope formed using points (4,6) and (8,0) is $\dfrac{3}{2}$

Step-by-step explanation:

Given as :

The points are (4,6) and (8,0)

( $x_1$ , $y_1$ ) = (4,6)

( $x_2$ , $y_2$ ) = (8,0)

Let The slope that formed = m

So,

slope = m = $\dfrac{y_2 - y_1}{x_2 - x_1}$

m = $\dfrac{0 - 6}{8 - 4}$

Or, m = $\dfrac{6}{4}$

∴ m = $\dfrac{3}{2}$

So, The slope formed using points = m = $\dfrac{3}{2}$

Hence , The slope formed using points (4,6) and (8,0) is $\dfrac{3}{2}$ Answer
