Answer:

\boxed{x = -14}

Step-by-step explanation:

Solve  \: for  \: x:  \\  \implies  - x+8 + 3x=x - 6 \\  \\ Grouping  \: like \:  terms,  \:  - x + 8 + 3x = ( - x + 3x) +8  :  \\ \implies ( - x+3x)+8=x - 6  \\  \\ 3x - x=2x: \\ \implies \boxed{2x} +8=x - 6  \\  \\ Subtract \:  x \:  from \:  both \:  sides:   \\ \implies( 2x- \boxed{x})+8=(x- \boxed{x})-6  \\  \\ 2x - x = x:  \\ \implies \boxed{x}+8=(x-x)-6  \\  \\ x - x = 0:  \\   \implies x+8=-6  \\  \\ Subtract \:  8  \: from  \: both  \: sides:  \\ \implies x + (8 -  \boxed{8}) = -   \boxed{8} - 6 \\  \\ 8 - 8 = 0 : \\ \implies   x =  - 8 - 6 \\  \\  - 8 - 6 =  - 14 :  \\ \implies  x =  - 14

A rectangle has vertices located at (–4, 4), (2, 4), (2, –4) and (–4, –4). What is the length of a diagonal of the rectangle?
Allisa [31]

Answer:

A diagonal of this rectangle has length 10.

Step-by-step explanation:

The vertices (-4, 4) and (-4, -4) have the same x-coordinate (-4) and different y-coordinates (4 and -4).  These two points are the endpoints of a vertical side of the rectangle which has length 4 - (-4) = 8.

Similarly, the vertices (2, -4) and (-4, -4) have the same y-coordinate (-4) but different x-coordinates (2 and -4).  To find the horizontal dimension of the rectangle, we calculate 2 - (-4), which comes out to 6.

Thus, the width of the rectangle is 6 and the length is 8.

Using the Pythagorean Theorem, we find the length of a diagonal as follows:

d = √(6^2 + 8^2) = √(36 + 64) = √100 = 10.

A diagonal of this rectangle has length 10.
