False because you can only use the Pyth. Theorem on right triangles which may not necessarily be ALL similar triangles.
Answer:
x=0.625
Step-by-step explanation:
-(-2x+1)=9-14x
distribute:
2x-1=9-14x
add 1 to both sides
2x = 10-14x
add 14x to both sides
16x=10
divide by 16 to isolate x
x = 0.625
check:
-(-2(0.625)+1) = 9-14(0.625)
0.25 = 0.25
Answer:
x = 6
Step-by-step explanation:
First, separate the problem into 
Then, Subtract 9 from both sides of the equation. 
Simplify. 
Multiply 3 to each side, which will give you -2x = 4x - 36
Subtract 4x from each side -2x - 4x = 4x - 36x - 4x
Combine like terms: -6x = -36
Divide both sides by -6
Your answer should be 6
