Lets w is width
length = 2w - 3

w(2w - 3) = 14
2w^2 - 3w = 14
2w^2 - 3w - 14 = 0
(2w - 7)(w + 2) = 0

2w - 7 = 0
w = 7/2 = 3.5

l = 2w -3 = 2(3.5) - 3 = 4

answer:
width = 3.5
length = 4

Please help! Im so stuck on this and cant figure it out

Reptile [31]

First, we split the figure into two shapes, a triangle and a trapezoid. First, we know that the length of the base of the right triangle is 2, because in a 30-60-90 triangle, the side next to the 60° is half of the hypotenuse. Then, the length of the height would be 2 times root 3, which is 3.46410161514. Height is 3.46410161514 meters and base is 2 meters. We multiply the base times the height, and we get 6.92820323028 meters squared. This is the area of the triangle. Since we know that the base of the triangle is 2, we can do 5-2 to find the first base of the trapezoid, which is 3. We know that the height is 3.46410161514, the first base is 3, and that the second base is 5, so we plug it into our equation which is base1 + base2 over 2 times the height. We plug it in and get approximately 13.85641. Then we round to the tenths place, and we get 13.86 meters squared of the figure. Brainliest?

mr.white can travel for 6 hours while taking 3 breaks of 10 mins each once he had to travel for 36 hours how many minutes in bre

arlik [135]

If he once traveled 36 hours and he takes 6 hour trips you do
10x3=30 so every six hours he takes 30 minute brakes then 36 divided by 6 equlas 6 you would do 30x6= the answer!!! (Btw i do 6th grade math)

Plot the image of point D under a dilation about the origin (0,0) with a scale factor of 3.

babunello [35]

Answer:

D'(-6, 0) is the image of point D(-2, 0) under a dilation about the origin (0,0) with a scale factor of 3, as shown in attache figure below.

Please check the attache graph below where you can check the plot of the image D' of point D.

Step-by-step explanation:

As the point D on the coordinate plane has the vertex location

D(-2, 0)

The rule of dilation about the origin (0,0) with a scale factor of 3:

The rule states that if we dilate the point, let say D(-2, 0), under a dilation about the origin (0,0) with a scale factor of 3, all we need to multiple the coordinates of the point D with 3. The result will be the image of point D.

P(x, y) → P'(3x, 3y)

D(-2, 0) → D'(-6, 0) ∵ (-2×3, 0×3)=(-6, 0)

Therefore, the image of point D under a dilation about the origin (0,0) with a scale factor of 3 can be plotted at the location D'(-6, 0).

So the new location of D' is (-6, 0).

D'(-6, 0) is the image of point D(-2, 0) under a dilation about the origin (0,0) with a scale factor of 3, as shown in attache figure below.

Please check the attache graph below where you can check the plot of the image D' of point D.
