The length of a rectangle is six more than double the width. If the perimeter is 102 inches find the dimensions
stiks02 [169]

Answer:

width = 15 inches

length = 36 inches

Step-by-step explanation:

To solve you need to find the width...

width = w

length = 2w + 6

the perimeter is all the way around the area, so..

2w + 2(2w + 6) = 102

because there are 2 widths and 2 lengths in a perimeter.

Solve for w:

2w + 4w + 12 = 102

subtract 12 from both sides and combine like terms...

6w = 90

divide both sides by 6...

w = 15

the width = 15, and the length = 2(15) + 6 = 36

What is the length of the longest side of a triangle that has vertices at (7, 6), (7, 1), and (-5, 6)?
iren2701 [21]

Answer: The Answer is going to be B.

Step-by-step explanation:

We can find the distance between each pair of points using the distance formula Sqrt((x1-x2)^2 + (y1-y2)^2),(x1 and x2 are the x ordinates of each point, and y1 and y2 are the y ordinates. Sqrt stands for square root, and ^2 is to the power of two.

Using this we can find the side between 7,6 and 7,1 is 5.

The side between 7,1 and -5,6 is 13

The side between 7,6 and -5,6 is 12

After using the formula we can conclude the side between 7,1 and -5,6 is the longest, and it equals 13. Therefore the answer is B.
