Hello there, and thank you for posting your question here on brainly.
A trapezoid is not possible to have for obtuse because it would look more like a diamond. Also, if it had 4 obtuse angles, it would have 6 sides.
Hope this helped!! ☺♥
Y= 1.5x+8
You do rise over run
y/x = y2-y1/x2-x1
8-5 divided by 0-(-2)
3/2=1.5. That is your slope.
Then you look for the y-intercept which is (0,8) So you plug in the equation for y=mx+b and you get y=1.5x+8
The equation that describes the which gives the area of the pen, A, as a function of x, the length of fence parallel to the barn is A = 130x - x²
<h3>How to find area of a rectangle?</h3>
The pen is rectangular. Therefore,
area of a rectangle = lw
where
Therefore,
perimeter = 2w + l
perimeter = 2w + x
130 = 2w + x
130 - x = 2w
w = 65 - 1/ 2 x
A = xw
A = x(65 - 1/ 2 x)
A = 65x - 1 / 2 x²
Therefore, the function that represents A, the area of the pen is as follows:
A = 130x - x²

8.1 x 10^-8
When going in the negative direction, the further left you go, the smaller the number.
These number would order smallest to largest as:
3.4x10^-10
9.2x10^-9
8.1x10^-8
8.2x10^-8
7.3x10^-5
