A rectangle or piece of paper has a width is 3 inches less than its link it is cut in half along a diagonal to create two congru
kolezko [41]

The length and width of the rectangle is 11 in and 8 in respectively.

Step-by-step explanation:

Given,

The width of a rectangle is 3 in less than the length.

The area of each congruent right angle triangle = 44 in²

To find the length and width of the rectangle.

Formula

The area of a triangle with b base and h as height = \frac{1}{2}bh

Now,

Let, the width = x and the length = x+3.

Here, for the triangle, width will be its base and length will be its height.

According to the problem,

\frac{1}{2}×(x+3)×x = 44

or, x^{2} +3x = 88

or,x^{2} +3x-88 = 0

or, x^{2}+(11-8)x-88 = 0

or, x^{2}+11x-8x-88 =0

or, x(x+11)-8(x+11) = 0

or, (x+11)(x-8) = 0

So, x = 8 ( x≠-11, the length or width could no be negative)

Hence,

Width = 8 in and length = 8+3 = 11 in

Find the midpoint of the line joining A (3,5) and B(1,3)​
MaRussiya [10]

Answer:

(-1 , -1)

Step-by-step explanation:

x_1= 3 \\ y_1= 5 \\ x_2=1 \\ y_2= 3

midpoint \:  = ( \frac{x_2 - x_1}{2}  \:  \frac{y_2 -y_1}{2} )

=(  \frac{1 - 3}{2}  \:  \frac{3 - 5}{2} ) \\  = ( \frac{ - 2}{2}  \:  \frac{ - 2}{2} ) =  \\ ( - 1 \:  - 1)
