Step-by-step explanation:
Using Pythagorus theorem:

Therefore,

Answer:

Step-by-step explanation:
In order to make d the subject of the formula, you need to isolate it.
- You started with d-7 = 4d + 3/e
- Move 4d to the left side by subtracting 4d from both sides to cancel it from the right so you have...
d - 7 = 4d + 3/e This will leave you left with -3d - 7 = 3/e
-4d -4d
- Then move over the -7 by adding 7 to both sides...
-3d - 7 = 3/e This will leave you left with -3d = 3/e + 7
+7 +7
- Finally to get d by itself divide both sides of the equation by -3 and you'll be left with...

- You can cancel out the 3 in the -3/3e and make it -1/e so your final answer will be

The Pythagorean theorem is a^2 + b^2 = c^2. You use it when solving for the sides of a triangle.
I don’t think those are similar... not 100% sure tho. I think they need 2 matching angles to be similar.
Answer:
Pretty sure its A and B
Step-by-step explanation:
Slope is -6/5, so that leaves just A B and E
Plugged it in, only A and B were correct
