Answer:
That would be the side-side-side (SSS) postulate, which states that if all the sides of a triangle are in a fixed ratio to all the corresponding sides of another triangle, then the two triangles are said to be congruent.

Answer: x=9
Step-by-step explanation:
7x+43=106
subtract 43 from both sides
7x=63
divide by 7
x=9
Answer:
1
Step-by-step explanation:
(f+g)(1) = f(1) +g(1) = -1 + 2 = 1
__
The pair (1, -1) in the definition of f tells you f(1) = -1.
The pair (1, 2) in the definition of g tells you g(1) = 2.
Answer:
±sqrt(T*L/m)=v
Step-by-step explanation:
T=mv^2/L
We want to solve the equation for v
Multiply each side by L
T*L=mv^2/L
*L
T*L=mv^2
Divide each side by m
TL/m=mv^2/m
T*L/m=v^2
Take the square root of each side
±sqrt(T*L/m)=sqrt(v^2)
±sqrt(T*L/m)=v
