Answer:
The equation is true.
Step-by-step explanation:
Simplify. Combine like terms:
3x + 15 = (2x + x) + (10 + 5)
3x + 15 = (3x) + 15
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:
3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)
3x - 3x = 15 - 15
0 = 0
~ True. The two expressions are equal to each other.

Group the common terms together
3x + 5x - 5 + 1
then add or subtract them
8x - 4
I'm pretty sure that you can not make these improper fractions; improper fraction just means the top number is bigger than the bottom. like 3/2 would be considered an improper fraction
The triangles are similar because they are the same shape. :) Good luck
Use PEMDAS and you should get 225
