Answer
8.5
Step-by-step explanation:
43 - 3d = d + 9
43 = d + 3d + 9
43 - 9 = 3d + d
34 = 4d
34/4 = 4d/4
8.5 = d
btw its a bit rude just to delete my answer you shouldve just asked for me to show an explanation

Answer:
Step-by-step explanation:
<u>There are two roots:</u>
<u>The function is:</u>
- f(x) = (x - 3)(x - 2)
- = x² - 5x + 6
Answer: x = 20 degree
3x = 3×20 which is 60 degree
And the other one is 100 degree
Add all the number 100+60+20 degree is 180 degree
Area = 36 = length*width
Then, while the area is constant the product length*width is constant.
Length and area are inversely related.
That means that to keep the same product (area), length vary in inverse proportion to width.
If you increase length, widht has to decrease to satisfy this relation:
width = 36/length
Of course, you can also say: length = 36 / width.
